I read about it, here: https://github.com/doitsujin/dxvk/wiki/Common-issues (The 32-bit games Section), so that's the issue then?

I'll give it a try using the Large address aware tweak, will report results when tested.

Edit:
Tested, Tweak didn't fix it, still the same issue.

Two things which helped me in the past in similar situations in case of 32-bit games:

• disable shared memory for pulseaudio or at least set it's size to significantly smaller value than default 64MB (put enable-shm = no or shm-size-bytes = 1048576 in ~/.config/pulse/daemon.conf and restart pulseaudio daemon)
• set d3d9.evictManagedOnUnlock = True in dxvk.conf

Thanks for your hints. Unfortunately they don't help.
d3d9.evictManagedOnUnlock = True: leads to broken textures, game still crashes.
The pulseaudio settings didn't have any visible effect for me.

Regarding the Large Address Aware flag, you could try patching the exe manually.

I use this program to do it: https://github.com/randomstuff/pe-set-laa

This helped me resolve a lot of crashes with 32bit games, maybe it will also help your case too.

Thanks, I tried it, still no change.

I will try and reproduce this sometime this week

Nice!
For installing ALOT, I used this: https://github.com/MassEffectModder/MassEffectModder/releases (409 contains Linux Binary release)

For installing ALOV, I manually copied the data to the appropriate folders.

I've had the same issue with World Of Tanks behaving the same way on Ubuntu 18.04 (liqourix kernel) with my i7-4970K, 8GB RAM & Nvidia GTX980. I've tested different wine/proton versions, different kernels, lighter DE's, tweaked vm swappiness values and God knows what else by this point. But never gotten to play like 2 or more matches before the game freezes and i see that pesky DxvkMemoryAllocator error in the log. Keeping other apps and stuff at a minimum just seems to buy some time at best before it crashes

BUT: I think i finally found a solution that really works:

in terminal, just:

echo 1048576 | sudo tee /proc/sys/vm/min_free_kbytes

Now i don't know for sure, but it leads me to thinking that the memory allocator does only care about what's reported as "free" mem and really doesn't try to allocate if it's any less than what it wants?
Anyway i think everybody should give this a go! I've played several matches in a row now, highest graphical settings possible (enhanced client) with no hiccups and even had chrome running in the bg etc.. Damnit i'm gonna try HD textures now xD

EDIT: should the game still crash, i'd suggest raising that number a bit, not TOO much tho.. i tried 4GB and my system really didnt like that lol

Thanks for the hint, I tried this(1 and 2GB), but still the same.

Can confirm for Galactic Civilizations III (the game appears to freeze on maps if they are large enough — and then a game-specific error message appears), but I can only run GalCiv3 on unmodified Proton 4.2-9 (it crashes outright on loading screen under 4.11 and 5.0; my regular Wine is 5.0). I suppose I’ll have to manually replace Proton 4.2’s version of DXVK with the latest one to investigate this issue.

And yes, it’s a 64-bit game.

@K0bin
I've already tried that, see above.
