I ran the game again last night with the ROTTR.exe process opened up in process hacker. There were 8 threads that seemed to be the same name and one with NV something in the name. I am not sure what I was looking at with all of those threads but the highest was floating around 9 on usage and the others were 4-8. There were quite a few other threads listed but they were all .2 and lower. The thread with NV in the name was the highest usage in the list. I wish I could alt-tab in this game so that I could grab some screen shots but it crashes when I try and the thread list is useless once it crashes.
Anyone know if maybe the exclusive full screen thing is why it crashes when I alt tab?
I am not sure if any of this matters for me or if this is something specific to AMD. I would certainly like to get the game running a little better maxed but I am hitting a VRAM wall with very high textures.
I have also noticed quite a few weird little things in the valley part of the map. For some reason the map becomes overly bright when I go from inside to outside, it's like the brightness is turned way up. I am also getting some weird flicker if I turn fast and for a little bit the ground textures were flashing. All of these things seem to be triggered by a certain point in the game, they stay that way until I reach a new checkpoint/goal with a long cut scene that transports you to a new area afterwards.
9.0 on 1 core means that you have about 25% of cpu performance to spare
if you want to see it while playing use 2 monitors or windowed mode
nvidia can use multithreaded rendering in dx11 but AMD does not have that so all load is on 1 thread thats why FURY X is so bad in 1080p but start to get more ground with 4K
if tomb raider was released with DX12 features Fury X will destroy everything even under 1080p as its computing power is masive but DX11 driver struggle to keep this card feeded with data
also asynch shaders will help alot with performance on cards which can use this feature
higher resolution means more works for graphic card so cpu bottleneck is lower
i also think that reason why AMD does not have DX11 multithread support is that they decided to spend their money and workforce on mantle and DX12 as it brings even better results than DX11 multithread also consoles allready have such option so even 1.6ghz 8 core is powerfull enought to run games like metro 2033 in stable 60fps (not even top of the line intel cpus can do that in some situations under DX11)Edited by OneB1t - 2/3/16 at 1:09pm
