Odd one this.
Tested in both the Linux and Windows build of rpcs3-v0.0.23-14056.
Game appears to run great. You can enter a race or event, complete it no problem. Outside of shader caching pauses, absolutely no complaints. Looks sharp and runs really well.
But, when a race is finished and I either try to return the game's menu, or restart, I get a hard crash every single time. Oddly, the hard crash goes hand in hand with the game immediately being rebooted by RPCS3 which is not always how the emulator has behaved when other games have crashed.
I've explored all sorts of settings with no real fix. It seems unlikely this is a graphics / GPU issue, and more likely an issue to do with flushing / refreshing memory perhaps? I can retrigger the crash on command though by starting a race, pausing the game at any stage, and trying to retry / exit to main menu. As soon as I hit X - crash.
This happens every time on both Steam Deck, and a Windows PC with a 2080, i9 etc.
