Ive noticed roughly halfway through qualy (2 back to back sessions, different tracks) i had one huge fps drop, it sort of hovers around the 30 mark for about 5 seconds. then just stops, and the rest of the session is fine. Im going to try more Q sessions tonight and see if it does again. Its odd as there was noone on track with me on screen, there was no reason to hang up, unless the game was calculating something, i didnt check my temps. they generally dont get high in gsc. anyway just sharing..
