Hello @RubixPower, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/512#issuecomment-592102366.
proton 3.7x1 2020-02proton 4.11-12x1 2020-02
Compatibility Report
System Information
I confirm:
Log file
steam-214950.log
Symptoms
The launcher starts but when i launch/start the game there is the intro video and it crashes when after 1-2 seconds of the intro video.
Reproduction
I don't know how could others reproduce this issue because some people don't have this issue according to protondb's Total War: Rome II report.
Additional Info
The game run somewhat fine with proton 4.11-12 but it crashes frequently it got it somewhat fixed by installing d3dx11_42 but the game still crashes but not as many times as before.
I also found a report from 2018 (Proton 3.7.5-beta) which is old and not usefull.
