As a temporary fix disabling "fast_buffer_upload" in the config should fix the problem

[warior456]

there doesn't seem to be a difference with disabling that except even more fps loss

[RaphiMC]

Can you please retest with the latest version for 1.19.4/1.20. I recoded the fast_buffer_upload optimization and some other internals

[warior456]

I downloaded the mod today

[warior456]

@RaphiMC

[RaphiMC]

Can you send a spark report of the issue and the client log

[warior456]

Im on vacation rn I'll try to remember it
