Additional Comments

I used the same setup as the base game, 64-bit WINEPREFIX. 

Sometimes wher you launch the game, all characters and some other objects are partially o fully invisible.

There is no permanent solution for this moment (03.04.2017).

But this behavior not hapening every time, so you need to restart game 3-6 times.

Enabling anisotropic-filtering in video settings also helps to incresing chance of successful launch.

Also in my opinion, this problem happening less often with wine-staging, but this need to be proofed.

Added (23.09.2017):

If u use wine>2.6, setting REG flag 

HKCU/Software/Wine/Direct3D/CheckFloatConstants

to "enabled" can solve this. For me it bring no changes, but maybe u will be more lucky.

Thx @Fincer for info.

Enabling CSMT in wine-staging incress FPS near 30%.

Also u can try this:

Settings within options.txt:

maxResourceThreads = 16 

I did set it to 16 which is the amount of aviable Cores on a R7 1700X, Intel-Users did set this to lower settings then their max. amount of Cores which had something to do with Hyperthreading. Settings this to max. on Intel caused lower performance, i didnt see any performance-differences on my CPU. It significantly improved raising this value is all i recognised, it didnt seem to change performance after a specific point. 

Furter Performance-Improvements can be to set your Refresh-Rate to 60Hz with VSync enabled to work as a FPS-Limiter, the CPU is heavily bottlenecking within this game and lowering the CPU-Load via lower Graphic-Settings can help reducing some of the Lag-Spikes. CSMT-Enabled within Wine-Staging gives you a significant performance-boost. With the command cpuset you can improve the performance of the game further by disabling the first cpu-core. cpuset -l 2-15 -p (pid of the game).

Thx @SF for info

In some environments when u launch game throuth steam, it try to install "requested" software (directx, vcredist etc) each time.

For solving this:

1. Open your wine prefix

2. Navigate to 'drive_c/Program Files/Steam/steamapps/common/Grim Dawn/_CommonRedist'

3. This folder contains subfolders like 'DotNet', 'DirectX', etc. Open every folder and find file 'installscript.vdf'

4. Rename or delete this file.
