10GB vram enough for the 3080? Discuss..

Who's going back searching through posts now then eh?

But would you be able to launch/play FC 6 @ 4k with no FSR and max settings?

Probably not but then I found FC very repetitive and boring, got it for free with my CPU but only managed a few hours before I was bored so it's not a game I'd be basing my choice of GPU on.

@Nexus18 you wanted to see the updated performance on Far Cry 6 now, see below:

Spoiler: Videos

Benchmark with HD textures, no FSR at 3840 - 1600

Benchmark with NO HD textures, no FSR at 3840 - 1600

Benchmark with HD textures, no FSR max at 4k

Benchmark with NO HD textures, no FSR max at 4k

Gameplay with HD textures, no FSR max at 4k. I didn't record gameplay at 3840 x 1600 as it was fine, hovering around 70fps.

(Never uploaded anything to youtube before, not sure how long the "Processing HD" bit takes. But as the gameplay is the focus here, I'm not sure it matters too much. Otherwise, we can wait until it has done its thing)

Motion blur is off, but everything else is on in the above videos - Recording shaved 1 or 2 fps off, but otherwise is my general experience. It seems that using the HD pack and no other changes has a serious impact for me. If the only change is the HD pack, which is noted to require more than the vRAM I have available, it would indicate that in this instance, on my machine vRAM limits are being hit, surely?

Let's look at this the other way - The question I'd ask you @Nexus18 is if it can work for you at 10GB, why does it not on my machine? I would not expect the processor to be the issue at 4K. I am happy to try things to see if it does work, as if I can get it working within the 10GB limit on my machine, it would prove that vRAM isn't the issue wouldn't it?

Videos are private.

As said, I don't know why it worked fine on my end and you and tommy have issues with fps crashing to them kind of figures and staying at that, I find it strange that HUB didn't point out any issues in their 3080 vs 6800xt video yet they pointed it out in their 3070 video, however, their fps were higher reported than what other sites were reporting including the 6800xt performance figures i.e. my fps without any FSR had dips to 40s, same way a 6800xt has dips to 40s according to other review sites such as computerbase and pcgh.

You can see the exact settings I used here:

As mentioned yesterday, I tried installing it again to get more footage but game won't even launch for me, just stuck on the ubi connect loading screen, tried installing to different drives and doing verify thing.

Out of interest, be good to see if enabling FSR resolves your issues or/and reducing the other graphical effects by one notch (whilst keeping HD textures enabled and RT maxed).

EDIT:

How long did you play for until you encountered issues?

 

[Bill Turnip]

I expect FSR would resolve them, but then that means the GPU isnt rendering 4k, doesn't it? When it is expected to render 4k, it is hitting the VRAM limit.

I thought the point of this was to show 10gb was fine without lowering settings? If I was setting this up to play, I would change the settings, no issue with that. I'm more interested to see if I can show 10gb is or is not the limiting factor to a full bells and whistles experience without upscaling.

How do you unprivate videos? You may see something obvious I have incorrect. Like I said, happy to change settings to see if I can show the issues one way or the other.

Hence why I want to see what happens with FSR in your case or/and adjusting other settings (outside of HD texture pack and RT)

You can see my video above it plays fine, however, dips to 40s with fps being around 50 is not an enjoyable experience i.e. in this instance, on my machine, the grunt isn't there, same way a 6800xt achieves similar fps as you can see in my video i.e. it also doesn't have the grunt:

Spoiler

I suppose you could say the spikes/fps spikes seen in my video are down to vram being cleared/new assets being loaded in/out on my end but obviously that is far more bearable than having fps plummet and stay locked like what you see, again, why this happens, I don't know, same way I don't know why it also happens to some 3090 users too.

In your video manager on YT, you'll see a drop down option.

 

[Bill Turnip]

Also, I've had a look at your settings and there doesn't seem to be anything shown about FSR variable shading. Your scroll bar seems to be at the bottom, so it simply doesn't show on your video? Maybe due to it being an older version of the game.

Using FSR on quality mode brings everything to a near constant 60fps, until it gets to the end of the benchmark when it drops to around 45fps. This seems to be expected behaviour as the gpu is rendering a lower resolution.

I've unprivated the videos now, I think.

Yup I believe it was added in later on, iirc, it is like a resolution based setting for dark areas i.e. reduces res. to help with performance in dark areas. Personally I would keep it off, same way I keep CAS off as it increases all the TAA artifacts i.e. shimmering/aliasing and motion clarity issues become even more apparent.

What about in gameplay? To me it sounds like something doesn't clear/re-allocate vram properly hence why your FPS plummets to never go back up again even when you change area (as I showed with my 100% sole vram limitation in cp 2077, as soon as you go to a new area, fps and frame latency returns to normal as CPDR have obviously engineered the game to behave in that way when it comes to vram/asset management), again, why this happens to you and not me, I don't know, maybe you can try taking a screenshot with MSI AB to see if that resolves the issue, same way it did for Joker

Benchmark performance is as expected - I had a dip at that area when using UW 1600 too.

In the video you most recently linked, he is using a 3080ti. I haven't watched fully, so may be missing a point, but a 3080ti has more vRam than 10GB, so doesn't seem relevant here?

Gameplay using FSR is fine, but again, rendering at a lower resolution. This is still in line with expectation. If I was setting up to play, I would use FSR, but this is a test of VRAM limit. 10gb APPEARS to not be enough to render 4k gameplay in this instance.

It's very relevant.... Why does he encounter a massive fps drop too? (despite having 12GB vram) And more importantly why does taking a screenshot fix it? Given we are talking about your issue of fps plummeting/game being a slideshow and linking it to a shortage of vram.... Same way there are "some" 3090 owners experiencing exactly the same behaviour i.e. if it was 100% a vram issue and nothing to do with the game development or/and an issue with the game/nvidia, why are "some" people with higher vram gpus getting the exact same issues of fps dropping? Surely it can't be vram on their end given they have the recommended amount? Right?

So in your scenario on your machine:

- it seems FSR resolves your issue and you can play it fine without sacrificing other settings including the HD texture pack? Which again you would have to use FSR even if you didn't encounter the FPS issue because if we use the gospel site that the inner knitting circle love to use, we can see a 6800xt (which is the 3080 competitor and has 16GB vram) achieves the same fps as per my video thus you "need" to use FSR regardless unless you're happy with 40s-50s fps:

Spoiler

So do you concur that it is a non issue then and people are just making a big deal out of it because it suits their narrative/agenda?

Thanks Bill. As expected.

 

[Nexus18]

Tried installing FC 6 for the 5th time and still the same Clearly needs more vram on my side now....

@TNA you really are missing out on a well developed game here

 

[Bill Turnip]

Ah, I think I see what you're getting it. Are you referring to around 3:40? If so, he states taking a screenshot fixed it, but never actually showed it. It just cut back to his current video, so that's anecdotal, not evidence.

My 4k videos show no dropping from area to area, but slideshow performance the whole time. This may be a separate issue than the one he supposedly solved.

FSR solves the issue as it means the GPU is not actually generating 4k. This is expected. So for me yes, FSR does solve the issue in the same way, but in the same way that not running at 4K would. Not running at 4k means less vRAM is required, so you are back under 10GB.

This is why upscaling is important, because 10GB isn't enough for 4k in this case. On the whole, it is enough, for me at least.

Stupid game anyway...

Yes exactly that bit.

I think you're missing the point here.... he showed precisely what happens when he enters the new area with the fps plummeting to 7 fps (it also happened in other areas too) i.e. the same thing that happens to you and Tommy, maybe not exactly the same conditions but it is the exact behaviour where fps is slideshow level..... I don't think a reputable enough channel like Joker would lie about taking a screenshot which fixes the issue, why would he? Seems like a bit of a silly comment to make, let alone bit of an odd one to just come up with out of nowhere....

Slight side note, out of interest then, you would agree that the majority of the inner knitting posts are also "anecdotal" too then given they haven't posted a single piece of evidence from their end when it comes to all the other games with supposed vram issues i.e. halo, re village, doom eternal?

So what are your thoughts on the 6800xt performance then? Based on the performance figures of the gospel review sites, would you say the 6800xt doesn't have:

- enough vram

or

- enough grunt

For a locked 60+ fps experience @ 4k without FSR?

Do you think enabling FSR would allow a 6800xt to get that locked 60+ fps?

Spoiler

PS. watch my video above again and keep a close eye on the allocated and dedicated vram and you will see the 10GB being "exceeded", surely when that is happening, my FPS should have plummeted too if this was a 100% vram limitation i.e. no other factors at play? Then go and watch my CP 2077 video and look at the behaviour there.

 

[Bill Turnip]

Some, certainly. Some of your own also, such as the video you most recently linked. The behaviour in that video is different to mine (He claimed to start with fine fps, then it tanked. Mine is tanked from the off) It's why I'm posting videos showing the issues, and trying to engage with you to work out why it isn't happening. If vRAM isn't the issue, there are only so many settings to play with. The only one I've seen that so far works is FSR...which renders at a lower resolution, and reduces vRAM requirement anyway.

If it works on yours, there must be a reason that it doesn't on others, and the answer must therefore be repeatable on another machine. Unless you have an nVidia control panel setting which is over-riding the game maybe? I think mine is all stock, apart from limiting frames to 141 for gsync reasons.

I don't think a reputable enough channel like Joker would lie about taking a screenshot which fixes the issue, why would he?

Is it reputable? I don't follow, so have no idea. I have no reason to dispute, but I also have no reason to believe without evidence.

Also, the 6800XT isn't the point of this thread. If it has sufficient vRAM but not enough grunt, that's a different issue for that card. I imagine FSR would solve it (that's the point of upscaling), but don't know as I don't own one. But the picture that you're using from ComputerBase in the spoiler literally states "HD textures not possible". Do we just ignore that?

allocated and dedicated vram and you will see the 10GB being "exceeded", surely when that is happening, my FPS should have plummeted too if this was a 100% vram limitation

This is what I am trying to get to the bottom of. Mine does not seem to exhibit the same behaviour.

Cheers Bill, I see it is choking hard in actual gameplay at 4K max settings. It's exactly the same as PCGH and Computer base saw. Also the same as what Tommy and Gerard saw, but they were in different parts of the campaign further on in the game. @tommybhoy, you still got your video?

Here is how it runs on a stock 6800 XT MBA card with Smart Access Memory at 4K max settings in actual gameplay. FPS roughly 60-75 or thereabouts.

Here is how it runs on a overclocked 6900 XT Toxic card with Smart Access Memory at 4K max settings in actual gameplay. FPS roughly 80-100 or thereabouts.

Here is the benchmark sequence running on my overclocked 6900 XTXH.

Here is the benchmark sequence running on my 3090 FE overclocked.

Here is the benchmark sequence running on my 6800 XT overclocked. (this was taken when the game first launched so performance should be better now)

But the picture that you're using from ComputerBase in the spoiler literally states "HD textures not possible". Do we just ignore that?

This is what I am trying to get to the bottom of. Mine does not seem to exhibit the same behaviour.

And that's why I am bringing his video up as well as what "some" 3090 owners over on ubi support forums posted with regards to fps plummeting too i.e. they are having awful fps issues too and yet we have ruled out the amount of vram as being the factor so what is causing their issues?

If yours is plummeting straight away, why isn't mine? Obviously different scenes but those msi ab statistics don't lie..... All my nvidia control panel settings are default too, I turned off vsync for the purpose of testing (would always have it set to on for gsync), literally only other things I can think of:

- windows 11
- rebar off (will be automatically off)
- game mode on, hardware accelerated scheduling on
- rivatuner fps cap set to 171 (never get fps that high so won't make a difference)

The 6800xt isn't the point of this thread but it proves the point I and many others have been making..... that despite it having more vram than the 3080, it is achieving the same FPS as my 3080 does hence the need for FSR on "both" cards i.e. even if on my system, my 3080 had more vram, it would still be achieving similar fps as reported by reviewers for the competing gpu i.e. 6800xt. Like I said, Matt and co. love to refer to computerbase and pcgh site for their 3080 FC 6 results but for some reason their 6800xt performance figures aren't reputable? Not see the flaw here..... inb4 matt posts his highly tuned setup with AC for cooling And just to be clear, I'm not disputing their 3080 results, same way I'm not disputing your experience, I'm just stating it doesn't happen on my end, same way it doesn't seem to be a problem on HUBs end either.

Also, seems a 6900xt can't hold a locked 60 @ 4k either without FSR, inb4 matt posts his golden sample too

It's simply stating that "both" cards need FSR regardless. It's a simple question to answer:

So what are your thoughts on the 6800xt performance then? Based on the performance figures of the gospel review sites, would you say the 6800xt doesn't have:

- enough vram

or

- enough grunt

For a locked 60+ fps experience @ 4k without FSR?

Do you think enabling FSR would allow a 6800xt to get that locked 60+ fps?

And as you have perfectly stated:

If it has sufficient vRAM but not enough grunt, that's a different issue for that card

So why the big deal of having to enable FSR on the 3080 to solve the issues on your end and whoever else's end, however, at the same time, having to enable FSR on the competing card with more vram because said card doesn't have enough grunt as it is.... no one bats an eye lid....

Unless you're Matt and somehow seem to get very different results to every other reviewer samples....

I'm not sure what else I can do with fc 6 on my end as I've tried various things and it is just stuck on that screen, checked ubi forums to see if anyone having similar issue and nada.

@Bill Turnip Here's Tommy's video. It was choking so hard Tommy turned on voice narration by mistake, check the YT comments too.
