Hi, Unfortunately I cannot finish one single race in Rfactor 2, in contrast to AC, Pcars, Rfactor 1 or any simulator I have installed which runs without a glitch. In rF2 every attempt I got a "task host" error and / or a Nvidia driver failure. At first I was suspecting of my track but I realized there's nothing to do with it. It happens with pure ISI content too.UPDATE->SEP-06-16, Now it's quite clear it should be something in the track. Hardware: GTX 980(I tried several drivers from 311 to 358, it doesn't make difference) i7-4790K 16Gb RAM There is a huge difference how other simulators deal with GPU hardware. Let's see this sample: rF2 is much more erratic on the GPU usage and GPU demanded power,as we can see at standard deviations. rF2 gives me 2 - 3 times more inconstancy of GPU management. While Project Cars (just an example) keeps the GPU usage around 89% all the time, rF2 floats from 77 to 89. It's not a matter of car and track combination, all pCars tracks show this result and the same goes for any rF2 combination. The result is a infallible Nvidia crash in all races when GPU usage goes near 100%. That's horribly frustrating because it doesn't seem to be a hardware issue in my end, otherwise I wouldn't be able to race Assetto Corsa and pCars flawlessly. I've just let a pCars race with 6 hours and all graphics maxed, 39 cars and no issues. I hope for some ISI help if possible.
