I used to get this quite a lot on another machine, and "seemed" to be caused by heat. Last night I had both the black screen
and also the minimise to desktop. For the black screen it comes back after a few seconds, and I just brake, and don't steer
for the minimise to desktop you just need to click on the icon the on taskbar to bring it back.
Which is fine if you already know that
It happened at one of the american speedways we ran at, which for some reason seemed to be heavy graphics
so I am sort of ready for it.
It happened a few times in practice, so for the race I used an app...can't remember the name... to slow the GPU clock
and memory speed by 5%, which would likely be enough to limit the heat, and it didn't actually black screen or min during
what little of the race I saw. Your car was sort of warping to me, no one else was, so I assume it was your car not mine
it was more like flickering than warping around, but I tried to not get too close anyway. I haven't looked at the server
replay, that might show whatever it was.
