Nvidia driver overhead?
The 10GB VRAM was the reason I didn't want to "downgrade" to a 3080, I knew it would be a problem just didn't imagine it would be a problem this soon.
Yup. Never go down on an upgrade. Idc how fast the bus is. I'm not going to be caught with the next Fury X.
Doubt it. that driver overhead doesn't seem to exist on the 3080Ti even though it’s the same driver.
The 3080Ti has more VRAM so it fits in the picture, pretty sure the game just wants All the VRAM for RT.
Okay I think some people are not realizing what is going on in some newer games. In the past we could look at vram usage and think oh that's just allocating and not really what it needs but things have absolutely changed in some newer games. What is going on now is that some games will actually start swapping out system ram without even allocating all of the vram. For instance if you have a 10 gig card a game may stop allocating at just over 9 gigs and go ahead and start using system ram if it's running out of vram. There are at least a couple of other games that have been doing this because you can see system ram usage go way up compared to a card that has more vram. For example if you took a 3080 12 gig and a 3080 10 gig you would see more system ram usage on the 10 gig model if it's vram limited.
Don't even know why it's a surprise. Did people really think 8gb was going to last forever? Yeah, sorry people overpaid $500-600+ for that paltry amount, but the writing was on the wall already.
I was responding to driver overhead. Also, why does the RX6650with less vram and a weaker GPU perform better than a 3080? The numbers both of these are producing are nowhere near being cpu limited so it’s not an overhead issue. And the 8gb card performing better than the 10gb card suggests it’s not a vram issue either.
I had a 3070 and a 2080 TI and even 2 years ago there were games where I had to lower the texture settings on the 3070 and in a couple of cases even at 1440p with ray tracing where as the 2080 TI had no such issues. Really even the 2070 and 2080 should have had 10 or 12 gigs as games then were already pushing close to 8 gigs at playable settings.
I've seen this happen with my 2060 in Shadow of the Tomb Raider, I ran out of VRAM and the game started pulling around 16GB and ran fine.
Well to be fair - I've cached at least 64 gigs from my enterprise NVME to be used in game or wherever windows needs it too. Maybe that's helping as well.
Based on what? Frame rate only seems to tank with <16GB cards.
I don't play 1440p, plus what's an outlier today will be the norm tomorrow. People are too quick to jump on the it's just badly optimized bandwagon. The RT effects do look awesome in this game probably the highest visual difference between RT off and max, than any other game I've seen.
Except the evidence here suggests that it IS a badly optimized game. Again, unless you can explain why a weaker GPU with less VRAM that isn't CPU limited is performing better than one with more vram and more powerful GPU, it's not only silly, but down right stupid to ignore optimization and jump straight to "VRAM! herp derp"
I largely agree with some prior comments on here - Expecting 8GB to be enough for a 2023 AAA title is just absurd. Although Nvidia is somewhat to blame here due to being stingy with their VRAM amounts. The 3080 should have been 12GB to begin with. The 3070 should have been 10GB.
I think some of this is just many years of stagnation and people largely didn't need to worry about VRAM unless gaming at 4K. Most of GPU history VRAM was always the #1 upgrade factor whenever new games came out and GPU's were very short lived mostly due to the rapid expansion of VRAM requirements.
Probably because AMD's implementation of RT uses slightly less VRAM? Who knows, you can't compare apples to oranges. The fact remains that the game needs more VRAM than any other for RT. If it wasn't a VRAM issue why would a 3060 12GB perform infinitely better than a 3080 10GB? Same architecture, same driver.
IDK what bug was that, I tried the game with AO and Shadows off, only with reflections and it was still unplayable on 2080Ti.
idk if it was a bug or people cant come to terms that their card cant handle it and its still in infancy, imo.
Not really... It will need to run lower settings than max due to the gpu anyway, reducing VRAM requirements.
What do you think is more likely. AMD managed to be better at RT in this one scenario despite being WELL behind nvidia in everything RT related…. Or…. There’s a glaring optimization issue? Do you have a source for AMD’s efficient use of RT? Or was that made up?
No, unless we're looking at different tests. The benchmarks of the prior page still show the Nvidia hardware being ahead in raytracing.
That's kind of my point. M76 was saying it's probable that AMD uses less vram with RT on, hence better performance on a 6650 vs 3080 even though it's a weaker GPU with 2GB less VRAM. There's a 1440p chart with RT on where the 8GB 6650 was matching a 10GB 3080 in 1% lows and beating it in average fps
The dev studio on this game is new. It's likely they aren't the best at telling DX12 what to do and how to do it
Sorry but that is not necessarily the case because it will be faster than previous cards that could already run settings that were close to the vram being tapped out. I mean look right now you can take a slow 3060 and run higher settings that impact the vram than a 3070 or 3070 TI. Stuff like textures have essentially zero impact on GPU performance other than vram.
