@MoerasGrizzly disable all layovers you might have, steam and nvidia experience and such. Also check win10, if you on one, backround tasks...there is bunch of stuff happening you might not be aware of. I have the same issue myself and sometimes its like driving braille...and hope you stay on track. These issues went away for a while but one of the recent updates (1.9?) brought them back. Majority went away after disabling layovers.
Nice races!! accidentally spin at second race first lap 3rd corner when someone slightly pushed me but anyhow funfunfun Couple of really tight battles on both races
