Really strange sensation now where I have slow down on the lowest graphics following the latest build. I have tried maximising performance, does nothing. The slow down can last from anywhere between 10 seconds to over a minute and happens across multiple tracks and mods (combos I tried were the DW12, FR 3.5, Mid-Ohio and COTA). Could it be that the install has been corrupted in some way? As a spectator of a 30 car grid I'm still fine.
