Witcher 3 Performance Discussion

I put this in the other thread, but I think I'll put this here too since it's an awesome guide:

Also, I might have missed this being posted here but nVidia has a really good tweaking guide to enhance viewing distance, density, shadows, mipmap quality and such:
http://www.geforce.com/whats-new/gui...ig-file-tweaks

"Our final shadow tweak enables additional bushes, trees, and clumps of grass to cast shadows on other game elements." I think a bunch of you wanted this.
 
Also make sure you read this if you are using CrossFire: http://support.amd.com/en-us/kb-articles/Pages/Optimizing-The-Witcher-3.aspx

Edit: This literally doubled my FPS using CrossFire. I went from 45-50 fps at 2560x1440 High to 85-90fps, and 70 fps at Ultra (HairWorks off). Definitely make this change:

Significant improvements to the performance of The Witcher 3: Wild Hunt can be realized on AMD CrossFire™ technology configurations by adjusting the anti-aliasing settings.
Users are encouraged to change the EnableTemporalAA setting from TRUE to FALSE in the application's Rendering.ini file. This configuration file can be found in the \bin\config\base folder of The Witcher 3: Wild Hunt's installation directory.
Users are strongly encouraged to alter this setting, as flat to negative multi-GPU performance scaling may be encountered if this optimization is not performed.

Alternatively, users can access The Witcher 3: Wild Hunt's postprocessing options menu and set anti-aliasing to off.

can confirm removing the APEX_ClothingGPU_x64.dll file DOES boost fps by 10 to 15 !

also there is NO noticeable difference in the game even on armor with cloth physics it still works

its likely that removing it forces the game to use the same file that is installed from your GPU driver...

im now getting 60fps with hairworks ON

Does this do anything for AMD users?

What sort of usage are you getting on each GPU? I'm running crossfire R9 280X's with the new drivers and am seeing about 80% usage on both. I disabled AA in the game menu (which I'm assuming does the same thing as modifying the EnableTemporalAA flag in Rendering.ini?).

Also, is there any difference between modifying fields in Rendering.ini versus user.settings in My Documents/Witcher 3?
 
Also the game doesnt use CPU much? my cpu usage stays at 50 - 60 on all 4 threads while it is maxed on something like gta v

I get between 80-90% in most scenes with CrossFire on. And yes, disabling AA in game does the same thing as disabling the Temporal AA flag.

Ultimately however I've reverted back to playing the game with a single GPU. Between the shadow flickering and the inconsistent frame times I was seeing with CrossFire at ~60 fps, I decided it's more enjoyable for me with just one card. Disappointing, so hopefully AMD can fix those issues.
