AC + CSP and Sol2.2 big fps loss RTX 3080TI/Samsung G9

[F248f106]

Hello guys,

I’m messing already quite some time with CSP and SOL2.2 in Assetto Corsa but it’s frustrating to not see any progress.
Without CSP I manage to get 120/170 fps but once I enable CSP (1.76) my frames are between 55 and 75 hz (more towards 60hz) I already disabled the tough stuff like Extra FX, smart mirror etc.
In AC video settings I lowered the shadow and reflection resolution to the lowest possible and rendering frequentie is set to static.
So the ‘big’ eaters are already off.
IMHO a loss of 70fps with CSP/Sol enabled is a bit to much.

My setup is:

Windows 10
RTX 3080 TI
I7-10700F 8cores
DRR4 32gb
Samsung 49” G9 connected with DisplayPort 1.4

These are the stats during a ride with a 20 car grid according to Riva tuner.

Thanks in advance!

Cheers,
Martin
