Additional Comments

Possible memory leak issue:

I did just a quick test for the game. However, it may have some memory issues, referring to the previous Wine test report:

"Crashing from time to time due to memory-issues. This is also a problem to windows-users, after a while of playing this game freezes. This happens because of the memory being bloated to a point where it is too much for the client to handle it."

"Switching to 64-Bit and enabling dx11 does completely solve or extremely reduce the occurrence of crashes of this kind."

"Another workaround is to reduce ingame-settings to reduce its memory-usage. (resolution, textures, view range, object details...) Just anything which affects memory-usage."

Invisible characters issue:

There is a known issue of invisible characters in Grim Dawn. As a workaround, users could have set "CheckFloatConstants" registry key to "enabled". I tested the game both ways: the registry key enabled and disabled. I couldn't reproduce invisible characters issue anymore though I ran the game multiple times with "CheckFloatConstants" disabled and played the game a while.

Users who encounter "invisible characters" issue may still enable the registry key value as described in HowTo section on this page. Personally, I can play the game without it. As I'm a Nvidia user, I don't know if the trick works for AMD Graphics users,however. Please see my test setup below.


I didn't need to install any DLL overrides described in the HowTo section on this page.

Steam software requirements popup:

I couldn't very well reproduce the issue regardless of multiple test runs. This issue has been described in the HowTo section, too. 

My test setup:

Geforce GTX 760M (drivers: 384.59)
Wine 2.17 Staging, clean 64-bit prefix. No DLL overrides
Steam version of the game
Arch Linux 64-bit

Tested with GLSL registry key enabled & disabled = works (Nvidia users only)
Tested with Wine-Staging CSMT option enabled & disabled = works (Wine Staging users only)

HowTo / Notes

[OLD] Characters partially invisible

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 


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

Steam version install software-requirements on every launch

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.

Changing localization (for old versions).

Game allow to change language via settings. After you select lang, it try to download translation-package.

But in wine this operation never ended succesfuly. This problem fixed in minor patch, but not listed in changelog.

For solving this:

0. Try to change lang in settings (other lang > select > download).

1. Open this official sub-forum.

2. Find your lang and download translation-package.

3. Open your wine prefix and navigate to 'Grim Dawn/localization'.

4. This folder must contain *.zip file, but it broken. We need only name of this file.

5. Copy downloaded package here and rename it with name from previous step. Old file must be removed.

[OLD] How to install VCRedist 2015 (old wine versions)

If u have problems with launching, like "Microsoft Visual C++ Runtime Error" errors, try this.

After installing vcredist2015, create new '*.reg' file, that contains:

Windows Registry Editor Version 5.00

and import this to registry of your wine prefix.
