Please try with proton ge latest

HeroicBotAPP•11/16/25, 5:49 PM

Please follow these instructions on using GE-Proton:

Head to the Wine Manager in Heroic, click the "GE-Proton" tab, and install "GE-Proton-Latest"
Head to the settings for your game(s) (icon on game card in library). In the "Wine Version" dropdown, select "Proton - GE-Proton-latest"
Rename your Wineprefix (path is shown in game settings), e.g. from
```
current-name
```
```
current-name
```
to
```
current-name_bak
```
```
current-name_bak
```
. To clarify: Rename the actual folder on your hard drive, do not change the option in the game settings.
Note: This will make game-specific configuration data (e.g. in-game settings or save files) unavailable. If this is an issue, let us know & we'll help you restore them.

Ddry-scarlet Please try with proton ge latest

you seem to be having this issue Games crash instantly when run by clicking "Play" but will work fine if run via "Run exe on prefix".

try disabling comet in settings (general settings, not game settings) > advanced

dry-scarlet•11/16/25, 9:39 PM

got rid of d3dcomp errs at least

radical-lime•11/16/25, 10:13 PM

radical-lime•11/16/25, 10:13 PM

radical-lime•11/16/25, 10:13 PM

radical-lime•11/16/25, 10:14 PM

@caringnickel240 would you be able to share a comet log of when it's crashing?

popular-magentaOP•11/16/25, 10:17 PM

Where do I find the comet log?

radical-lime•11/16/25, 10:21 PM

show file in folder

radical-lime•11/16/25, 10:21 PM

popular-magentaOP•11/16/25, 10:28 PM
