Grim Dawn

What works

This is for the GoG Version on the GIT VERSION of 1.9.6. The game is broken for 1.9.6 STABLE!

- Installation

- Single Player

What does not

Anything with 1.9.6 STABLE instead of the development version.

Without the below fix, parts of the textures are missing:

If you're struggling with invisible characters, do the following:

set HKCU/Software/Wine/Direct3D/CheckFloatConstants registry key to "enabled" (without quotations)

Registry key type: String Value (REG_SZ)

Requires Wine 1.9.5 or newer.

This is a known issue in multiple games:

Additional Comments

For installation instructions please check: http://www.grimdawn.com/forums/showthread.php?t=34333 and http://www.grimdawn.com/forums/showthread.php?t=18998 Those are for the steam version. Just omit the steam specific steps with the one from GoG. Installation was originally done with 1.9.5 so I'm only guessing it still works with 1.9.6.

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.

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 1.0.0.9.x 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.

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
[HKEY_CURRENT_USER\Software\Wine\DllOverrides]
"*msvcp140"="native"
"*msvcr140"="native"
"*ucrtbase"="native"

"*vcomp140"="native"

and import this to registry of your wine prefix.
