After upgrading to kernel 6.1.31, the opengl performance reduced to one tenth of the performance i had with kernel 6.1.12 After using the kernel config from debian 12 as a source for make oldconfig, the performance raised back to the old level. Reproducible: Didn't try
Created attachment 864595 [details] 6.1.31 kernel konfig with bad performance
Created attachment 864596 [details] 6.1.31 kernel config with good performance
Created attachment 864597 [details] 6.1.12 kernel konfig with good performance, differ only marginal to 6.1.31 bad

I'm not sure what you want us to do with this bug. It sounds like your kernel config was suboptimal, and you have corrected the issue yourself. Gentoo has no control over your kernel config unless you are using the sys-kernel/gentoo-kernel package.
I opened this bug in case this information is of any value for you. Feel free to close it.
