Description

It seems there are some random, yet fairly consistent crashes with Mario Kart 8, when using Vulkan and when Multi-Core Recompiling is set to be on. For full context, my system uses 16gb of Ram, includes a Geforce GTX 1070 with 8gb of Vram, and has an Intel i7 4770 and it seems as though the game crashes for some unknown reason, that is related to command buffer submission (from what is said through the log). I have tried each driver release from Nvidia 461.71 down to Nvidia 477.11, and it appears as though the driver releases didn't make much of a change regarding the issue happening. Playing the game in Single-Core Recomplilation seems to alleviate the issue happening, however it reduces performance. The Issue appeared to have happened for me with the 1.24.0 release of Cemu, however it happened much less for me, where as 1.25.0 seemed to have made it worse on my end.

I have tried the game with a variety of thread quantum settngs, however the issue tends to still remain. I primarily play with a thread quantum of 100000, which works well for a variety of other games including Breath of The Wild and Bayonetta 2.

The cup in-game that has shown very consistent crashes for me has been the Banana cup, in the first race within Dry-Dry Desert, however multiple cups sporadically show crashes. If requested, I can try and provide a video showing this.

After some time playing, I realized that this issue affects other games as well, including BOTW

Turn off the 60FPS split screen mod when you're not playing splitscreen.
It's know to cause a crash from what I've seen
