If you try to run the game from the windows vm yes the perf are bad.

But try to play these game from linux using wine/lutris ou protom/steam and you could be surprised

My games were running better (really better) on archlinux than windows 11. And i have also a nvidia card (RTX 3090 FE)

Did you cut the access to the firefox telemetry server (via PiHole i assume) before setting the parameters?

It could be Firefox trying to inform the telemetry server to not keep the data and/or logging the fact that you have disabled the telemetry.
