Game slows down after 2 minutes

Hi
Everything was normal for the first or second minute. and after the game slowed down to about 50% from its normal speed and it didn't go back to normal (but it still ran smoothly though (only in "slow-mo")). I've played with both high and low settings, but it hasn't changed anything either.

Can anyone help me?

(I get no prb with other Simus and i had no problem when i had my 2080ti)
Cheers.

Slow motion is in my experience usually caused by something related to the CPU. Are you able to get CPU load statistics/graphs for each CPU core when this happens, to see if one or more CPU cores is overburdened?

I have the same CPU as you, and have not experienced any problems like this.

 

Hi
my CPU monitor shows 30%
my FPS are good too but the game seems to run slow like glue. my whell reacts very slowly and the AI vehicles are fluid but slowed down.
When i used my 2080 Ti i had no prb :-(

 

Check for overheating. If overclocked, try without it.

 

absolutely none overheating no Overclock
Iracing, Rfactor2, PC2, Raceroom, ACC works fine
