PC VR (How much VRAM?)

i have fpsVR
does that show VRAM?

What you are trying to do is very hard to do when you are going the other way. Games will allocate VRAM based on what you have available. It might show that you are using 23GB of Vram but that doesn't mean that if you played the same game on a card with 16GB that the game would perform worse.

If you are thinking of upgrading, Uncle Petey's advice on the previous page is good. Push up the settings in Virtual desktop and in the game to settings that you think makes it look good graphically. See what frame rate you are getting, see what FPSVR is telling you and look at the performance monitor in Virtual desktop and see what is happening with the Latency in the various sections, encoding, decoding, game and network.

Then wait until the reviews of new cards come out and decide if the performance of the card you are looking at will give you the desired performance in the games you are playing.

IF you upgrade your GPU every couple of years, I wouldn't worry too much about Vram. 16GB is going to be fine for the vast majority of games out there.

What I would be worried about is performance. IF you are going to paying a £1000+ make sure the performance you are going to be getting in the games you play is worth that massive outlay. Remember Ray Tracing and AI frame generation are the main focus of the 5xxx cards, not raster performance. So the big spend might not give you what you were expecting and you might be better off just getting a second hand 4090.

how can i test VRAM in VR ?

In the case of DCS, there's an in game overlay but even without that, my system just gradually slows and gets terrible stutter when the VRAM is full. I'm not convinced 16GB will be enough to take my new system forward 4 years playing VR. I've just built a 9800x3d/64GB RAM system currently using the igpu just to get it all set up. Waiting for the gfx.
 
I think you will hit limits with 16GB, Nvidia talk about further memory compression in the 5000 series/DLSS4 etc but you basically want to chuck as much raw grunt and resources as you can at PCVR to get the most out of it.

When the Apache module for DCS came out (years ago now) the 'high' textures setting made anything under 16GB grind to an unusable halt in VR.

IMHO a 4090 will still out perform a 5080 in VR never mind the 5070 nonsense Jensen was spouting earlier in the week.

Thats my thoughts , 16gb is too low , maybe I'll wait for the 24gb version or get a 4090
 
As a 3090 user who purposefully skipped a gen I was eagerly awaiting the 5080, but the (pathetic) 16GB limit has pretty much killed it for me.

I think the only real options are 5090 (too pricey), 4090 used, or wait for a 5080 Super/ Ti that should have at least 20, probably 24GB. What do other 3090 users reckon is the best path?

P.S. If I wasn't into VR I would probably just stay on my 3090, but I've really got the bug now and the 3090 is really struggling now in raster grunt power for VR.

I've got a HOTAS, and tbh DCS was the reason I bought a headset, but I've not played much, and only just noticed the thread on here about DCS, over 100 pages lol
 
@ShiWarrior i guess one of the main questions is and not seen is asked, how long do you expect or want the repalcement card to last?
£2000 on a 5090 should last 5-10 years at a guess, wather the card lasts that long..
£500 on a 5060 for 4yrs vs a £2000 for 8years at a guess. as example.

also 4090s i thought were going end of manufacture shortly
 
not in one hit but there are various finace option possibly as well. im just putting it there as something else to consider. edit i.e the cost of the card your purchasign vs the life span
if 16gb is enough at the moment save some money over the next year to put towards a better one and wait for the various reviews to come out.
also in addation, you dont want another 4090 melting issue or bsod because manufacturing screwed up the ram design.

Yea I actually agree, in the eternal struggle for clarity, every bit helps.

With a 4080 and quest 3 and the resolution slider maxed, iracing@ 1.4x supersampling is crystal clear, easily my favourite looking sim, it just feels like you're driving a car.

ACC is unplayable with DLSS on, it's so ugly. That close to the assets, you really see the limitations - don't even get me started on FSR. It's a shame because it does feel like the handling is good, and I love the sound and FFB, but it's a dealbreaker. I've spent hours trying to get this game... not ugly.

AC 1.4x and 1.3x in content manager looks good. AMS2 looks better, competes with iracing but when I try to play it now I get annoyed by the cars floating into the side of the track and stuff, it just doesn't grip like I'm used to.

LMU has a bit of the ACC problem, but not as bad. I have to turn the SS down to 1.1x but then I seem to get my 72 fps. Or I think I do. I don't run any monitoring software in VR, none of it seems to work, iracing and AC having their own is a godsend, though it doesn't list vram usage I don't think... which brings me to my point...

I have no idea how much vram any of this uses lol. Afterburner never worked for me in VR, I avoid steamvr anything like it has aids.

Anyone know of some kind of simple VR performance chart I can throw into a static part of the screen, like on the dash

side note: I'm new to LMU, bought it the weekend, I never have trouble with race pace in iracing, or being one of the faster cars in a practice lobby, but I cannot figure this game out, like the computer does 2:00's at Spa, I can't break 2:03,and what's worse, I noticed I seem faster if I like don't even trail brake, because if I trail brake, it doesn't seem to give me the turning bonus I get in other games - infact, if I just brake at my normal hyper car breakpoints, then take my foot off the brake completely, it easily makes like any turn, even T1 spa it just whips around it. Maybe that's how these hypercars are to be honest? IDK I'll figure it out, just not today as I'm sick. There's probably just a very tight window for speed on turn entry that I'm not used to

My mini-review of it - the driving feels great, graphically it's nothing great, maybe with a 5090 you could run it at 1.4x with everything maxed, but I do 1.1x with everything maxed @ 72 hz, and things are a bit... blurry, and small. IDK why but only iracing gets the... scale of real cars right. But if I try to add a few points to other game's scale, they quickly feel weird. IDK. It's fine. It seems like a good game. The tires on the first lap are killers, and it was annoying having to keybind sim stuff I don't normally **** around with too much, but it feels neat how realistic that is so.

Iracing is just awesome in VR I agree... Looking for ward to the new 8k vr headsets this year! definitely going to need 5080 super/ TI or 5090

Thats what I've decided

So most likely a 4090

You could have bought my pristine hardly used 4090 for £1195 about 2 months ago which was the going rate, sold it partly because I thought prices would dip when the 5000 series were revealed, 4090's now seem to be going for around £1600+ :o :cry:

4090 at £1200 is a steal, the price has jumped cos the 5000 series is offering marginal gains.

5090 minus 30% is what 1.4k and that is before shipping an taxes... basically the 5090 is no better value than a 4090 it nets you more performance at a higher price

lower price ?
