Hi,
As the title says, I noticed that the 6.10.3 version of the liquorix kernel has a big performance bump compared to other kernel versions, around 10 - 15% more fps in games and in CPU benchmarks, for what I tried.

I made the comparison with liquorix 6.11 versions, liquorix 6.10.4, generic ubuntu 6.8 kernel, xanmod 6.10.3 and 6.11 versions. But I can't find a single kernel that matches the performance I get with this specific version.

So now, is there any explanation for this ?

System specs are : Ubuntu 24.04 - 32GB DDR5 - i5 13600KF - RTX 4080

EDIT : After further testing, it happens that disabling e-cores makes the different versions perform the same. So now the question is, how come 6.10.3 manages correctly p-cores/e-cores, but 6.11 doesn't ?

Some optimizations were added to Project-C to support P/E core configurations. Previous versions didn't understand this topology at all, so its behavior would be different.

Try adding the pcore_cpus parameter to your kernel boot parameters. For example, if you have 8 P-cores, pass in pcore_cpus=0-7.
