12GB vram enough for 4K? Discuss..

Nah, it'll just be a wall of the same video over and over again. 4k means using DLSS, which means the GPU isn't rendering 4k natively...But I'm getting off this roundabout as I'm in favour of upscaling, even if I don't agree with all the base points.

Looking forward to Spiderman's **** once it inevitably meanders to frame generation though. :p

The vid I posted earlier, the reviewer explains why he switches off FG in SM.

Yes according to Nvidia, it needs 16gb, but like myself you can't run DLSS3 to test, maybe requires extra vram usage for FG might not.

FG may require more vram but in the case of portal, it runs just fine when you use appropriate settings for what said gpus are capable of without FG/dlss 3...


I had a quick look and it does seem FG uses more vram on the whole, there are some games where it doesn't use much, if any more though i.e. plague tale.

As for the initial reasoning of this being why nvidia aren't bringing it to older gpus, so far they have only stated it is because of the optical flow accelerator processor and being 3-4x faster than what ampere has, words were: "the experience wouldn't be as good, would be more laggy and IQ issues".

Is it the game design or the card. CAnt see much texture wow factor from an HD texture pack

Like CP2077, Portal is a 'built' environment with many more reflective surfaces than games set in more natural environments, it's games set in these environments that showcase RT better that GPU's seem to struggle with RT.

But don't go selecting a particular set of settings - as we'll end up like the FC6 argument.

Portal non RTX isnt a hard game to run originally - seems the RT impact due to the environment as I mentioned above, cripples perf - and is unplayable on the 'I don't care about RT' GPU choice cards - I guess you wouldnt buy Portal RTX if you see no value in RT anyway.

It's down to remix being used to make portal fully path traced, remix is a nvidia tool and the portal implementation was also done by nvidias own studio so was never going to run well on amd.

Portal RTX is more about the lighting, gi, there are some areas with reflections but it's the lighting that really makes it stand out, it's the most advanced path traced title we have to date, even more so than quake etc. No doubt if it was done outside of nvidias ways, it probably would have ran better but that's kind of the point with remix, it's suppose to make it easier and quicker to add ray tracing to dx 8/9 games for modders.
 
If you're playing at 1440P you should be fine with 12GB of the 4070 Ti.

Now I'm not sure how much of this is actually "in use" vs how much is allocated but here is my 4090 at stock settings playing Spiderman Remastered in 4K with all ingame settings maxed out using Frame Generation and DLSS set to Quality.

12GB plenty for spiderman especially at 1440P. I did quite a few videos on it and it's a game you'll be wanting to use dlss or fsr anyway due to better IQ overall in terms of temporal stability and lack of shimmering:


4k:



3440x1440:


Being dx 12, it also got a nice boost from nvidias driver update a couple months back:

The game is totally not my cup of tea @Woodsta888 :p certainly not worth a hardware purchase for. Besides, why all these same games regurgitated. Better off waiting for some actual game to showcase RT from inception.

Actually, like the witcher RTX, portal RTX is free if you own the original. Aside the RT effects I cant see it being that much better looking texture wise than the original - there is very low draw distance required so no far away textures needed to load. Don't get the 16GB overhead. That said, apart from new purchases, which would be for RTX, there was little incentive to put too much effort into optimization. That game with RT off should run on a potato. Not THAT many textures in it, and those that are dont look any different.

actually i had some stuttering with witcher 3 rt 4k though the game plays pretty smooth with frame generation, and its fine with how it handles the overall pacing
someone was talking about witcher 3 rt using dx11 to dx12 translation that adds overheads, so its not created from the ground-up and i dont expect it to improve dramatically in performance
in fact the game has noticeable stutter without framegen so higher vram isnt going to help either

Yeah 12GB is fine for anything sub 4K, Heck even in most of the games I play at 4K I see sub 10GB used.

Days Gone - 8.9GB maximum used

Jurassic World Evolution 2 - 9.9GB maximum used

Probably, but if you need a 16GB card to play a remastered old portal game then something ain't right. Only gotta look at the steam reviews - I liked; Frames per second? More like - seconds per frame. :D

How much better looking is it with RTX off? 16GB worth?

It's probably largely down to the implementation method and the way the texture assets were updated/implemented in order to get path tracing working.

Only GPUs that can play it with dlss quality/balanced is the 4090 and 4080, everything else including the 3090ti need DLss performance at the very least.

TheRealDeal said:
It's the same as the 3080 10gb. It might scrape by but for the price it's not enough when the competition are giving out 8gb more. Like the 3080 i would feel a bit robbed and not sure of the future.
Click to expand...

I doubt you'll find any owners who paid £650-750 feeling robbed, only ones who should feel robbed are those who paid £1+k for rDNA 2 and ampere GPUs :cry:

3080 is holding up far better than the equivalent GPU i.e. 6800xt :) And it will probably be much the same situation with 4080 Vs 7900xtx
