Peut être une idée , trouvée sur le post consacré à la vr, mais sait on jamais :
"right click on the executable and then going to properties, compatibility, and then check "disable full-screen optimizations. I did this to both my steam.exe and rF2.exe." solution worked for me. I did it just to the rFactor2.exe and it worked! "
Thank's, I'll test
Pour info j'utilise W7
