This a bit of info regarding 32bit games and how you can prevent them from running out of Memory on Wine (aka crashing). I've originally posted this on gamingonlinux and I'm posting it here for further awareness among Linux users.
As some of you know, 32bit games tend to crash on Wine due to running out of Virtual Memory (not to be confused with System Memory). While this issue is also present on Windows, on Linux it is more affected due to the way the 2 OS's handle memory management.
To remedy these crashes on Windows, people changed a flag in the executables which allowed the games to use 4GB instead of 2GB. Just as on Windows, this method also helps greatly on Wine. I found a tool which can easily patch the exes on this thread (dates back to 2010):
https://www.techpowerup.com/forums/threads/large-address-aware.112556/ - All you need to run this tool is Wine with Mono and it's pretty straightforward to use: Browse to the exe file > Tick the checkbox to enable LargeAddressAware and Save it.
I've patched a few games and monitored their Virtual Memory usage, which went from around 3.6GB down to 2.5GB. Considering those games crash at 4GB they were inching close to the edge. Also be aware that this is not a magic bullet for all games, it works on a lot of games but not all of them.
Below I've made a list of all the games I tried it with and are now no longer crashing:
Colin McRae DiRT (1st game from 2006) - Max Details, with D9VK.
Racer Driver GRID (1st game from 2007) - Max Details, with D9VK.
Titan Quest Anniversary - Max Details, with D9VK.
Legend of Grimrock 2 - Max Details, with WineD3D 2.2GB / D9VK 2.9GB but stable.
These games do not crash but get very close to:
Tomb Raider: Anniversary
Tomb Raider: Legend
Tomb Raider: Underworld
I've originally knew about this back in the Win7 heydays and every time I tried to resolve the crashing issues somehow I never came across to trying this on Linux, until someone on Youtube suggested me to apply it to Titan Quest.
