3 980ti @1328/1903
Crossfire doesnt work with dx12 turned on.
And on max settings my 290x gets 26FPS Avg.. @ 4k
Must be something wrong with my setup if I barely get faster than that @ 1080P. Are you sure you are turning on full SSAA x4 because that causes the main performance drop.
Yeah no crossfire for dx12 yet it seems, 4gb cards have to run on high yeah, vhigh uses too much memory, it will cause stutters and probably crashes eventually.
Well judging by the min fps on this 980ti result, the game exceeding even 6gb is the cause since you should not get those kinds of minimums unless there is a pause while textures are loaded in.
To be fair i have only been playing it with FXAA so that is probably why. Very high textures without SMAA is fine with 4gb.
( i havent run the benhcmark yet either)
I rekcon it must be the SMAA that takes it over that.
In game I only run FXAA too, so wouldn't get too fussed over the vram impact tbh.
Don't have a clue, can only speculate that AMD haven't fine tuned vram usage as the 390 doesn't need vram optimisation-being the same core but lead platform.
Nv have put in a lot of work to overcome the 970 vram setup so Kudos to them for doing whatever they did and addressing the 970 memory management as mine never used to use>~3.8Gb up until a few months ago, same titles are using as much as the card has now, where as it was capped before.
Know I'm negative in some regards with both vendors at times but all round I'm more than happy with the 970, might change when it's replaced, but for now it's a real cracker of a gpu.
Updated to latest drivers with hotfix, turned off the new power efficiency feature and now dx12 actually works. In game its no longer a jerk fest like it was with dx12 on previous driver and smoother than dx11.
Check benches, on test 2 and 3 on dx11 i get a slight jolt a couple of times which account for the low fps, happens same place everytime. dx12 is much smoother, in game is very nice now.

It's weird just how much worse performance is in the last area under DX12. Nearly 18fps shaved off the maximum, despite a slightly higher minimum.
Interestingly, I've found the exact opposite with my 780 using DX12. Any run after the first is absolutely horrendous, shaving off a third of my performance and dragging me well under 20fps. It's not a thermal throttling issue, as I checked my clocks in Afterburner and they're rock solid. The issue also doesn't present itself in DX11, with subsequent runs on that being slightly better than the first run. Weird one. Must be a bug somewhere, either in the game or in the drivers.
Anything released recently just seems to come out with issues. It just seems like none is testing anything before they release it.
Quick buck. Release to market as soon as possible, patch later.
4 x TX @1430/1952
Memory usage @2160p
Titan X @ 1392/2005 - 3930K @ 4.4 - 364.51 drivers - both DX12 runs
8.5GB VRAM used at 1440P
Seeing has very high textures @1080p need 6Gb am not surprised to see this increase with resolution.
Could you add a 2560x1080 ultra wide section? I'll add my results later.

For some reason this game really hates my Vram overclock. Every other game runs happily at 7000MHz. If I have it even 92MHz over stock it crashes quite a lot. The extra GPU clocks help the game a lot though.
DX12 is much worse for me, and performance decreases with every run.
Does anyone else have the issue where the sun switches off momentarily when it passes behind Lara's head?
Only one small noticeable stutter towards the end of the final section with maxed textures and SMAA (which shouldn't really use up that much memory as it is shader based) on 3GB Vram.
I can add a 2560x1080p section.
Make sure you are using the same settings as in the OP - SMAA x 4
Do we have to use SuperSampling (SSAA) That make my internal res 10240x4320. Seems a little excessive, especially for anyone with less than 6GB Vram.
Last time I tried to launch the game with 4xSSAA, it just crashed.
Internal res for 4K would be 15360x8640.
