I harassed NIXXEN for months about it XD
you're actually right.
sooorry for not realizing that Mein Leben + RTX is not maxed. Turns out you can up textures from ultra to uber and brake 8GB vram pool.
only problem being I cant spot a difference while inspecting stills, let alone.. can you?
Windows A window has slight differences.
still dont see it.. i thought that i see it, most upper and furthest to the left window. turns out that's tree branches waving
is that a diff?
Uber has some tiny differences in shadowing (my guess is that it activates ambient occlusion), but the differences are incredibly small, need to look for them carefully...
Certainly not something that is noticeable during gameplay.
Yeah, adjusted for the slightly offset screenshots.
during gameplay? I CANT SEE THEM WHILE INSPECTING STILLS
image diff says RED is the difference: disregard trees whose difference due to waving trumps any possible IQ difference.
this is like ABX-ing 256 kbps mp3 vs 320 kbps, trying to find a difference, let alone figuring out which one sounds better. Still... toyota is right in principle - you can brake 8GB card on 1440p - today. In one game. With a silly setting.
Well, they could have insane level of texture detail that uses 20gb vram on ultra settings... and then maybe 8gb on medium settings. That would be the ideal anyway, for the game to be able to run on mid tier hardware on medium settings, but really pushing the boundary on ultra settings - a new crysis if you will
The one thing Nvidia didn't comment on in the reveal and I noticed later on the Nvidia marketing is memory compression.
There has been some work lately regarding deep learning for loseless image compression:
If they are using Tensor cores to compress/decompress textures the 10GB might not be an issue at all.
Nvidia already said in the Reddit AMA that in their testing 10GB was more than enough in their testing of a lot of games at 4K resolutions with Max settings.
And testing a lot of those games on my RTX 2080Ti at 4K I saw significantly higher Vram usage anywhere from of 8-10.5GB on most of those games. It really sounds like there is some texture compression going on that they really haven't talked all that much about.
Reminds me of windows Vista which used up all the system ram no matter how much you had installed. Ppl were suddenly buying more ram out of fear their systems would grind to a halt. They didnt know that vistas memory management was based on the principle that unused ram is wasted ram. MS heard all the complaints then altered the memory management and released windows 7 which was much more conservative in ram usage. I believe something similar happening with certain games which dynamically allocate as much vram as your GPU has (ie, Doom Eternal), but runs perfectly fine on cards with much less vram, even at 4k.
I doubt it - it's just nvidia trying to downplay (or as in this case outright lying about it) the importance of vram, and lack there of on the 3080... which they know is a tough sell for them...
Jeez, the lemmings all playing the same song like a broken record - this is true for some games, but far from all... alot of games will start stuttering if the vram usage goes close to full... shadow of the tomb raider is one such game, but there are alot of them...
No such problem for me on SOTR. Do not substitute user experience for universal experience. And yes, Mr. Lemming, the lemmings are all playing the same song like a broken record.
And you are playing at 4k with maxed out settings? No? Well then your input is kinda irrelevant.
From the review you linked : "If you want to play Ultra quality with Ultra HD as preferred monitor resolution, 8GB+ is advised."
"Graphics cards at the 4GB marker combined with the best quality settings will be sufficient, but the game eats it all. For Ultra HD and the best image quality settings, you will like the fact that your graphics card would have at least 8GB of memory. At both 1920x1080 and 2560x1440 we close in at 6GB~7GB used. Fact remains that with a 4GB card you will not experience any problems as the game simply tries to fill up memory wherever it can and is needed. Up to Full HD (1920x1080) any 4 GB graphics card of decent caliber will do the job well. I would like to see 6 GB for 2560x1440. If you want to play Ultra quality with Ultra HD as preferred monitor resolution, 8GB+ is advised. Again this is based on the best image quality settings."
I dont doubt you may be having issues or stuttering in the game, only doubt your certainty that its the vram. HH was not able to register more than 7.8gb on a 2080ti max vram usage. I'll take his word over yours. And again, user is not universal, unless you can show otherwise. Its always funny when a myriad of variables can induce stuttering in a game, but theres always some 'lemming' out there ready to pounce on the vram is the definitive cause.
Im sure many 1080ti and 2080ti users here can say that their memory usage even exceeds 8GB in many games as today.
From your exact qoute, he recommends more than 8gb for 4k... the reason is that the game stutters when you get close to full usage on a 8gb gpu.
I have tested it with both a 2080 and 2080 ti at 4k. On the 2080 ti it is smooth with everything maxed. With the 2080 it stutters with textures on ultra when you are in the hidden city (the most demanding area in the game) - but if you lower the textures to high the stuttering completely goes away... showing that it was purely stuttering due to vram swapping.
