Hi all, I have just upgraded to Windows 10, and this I think has affected F1 2015. The game now stutters and does not run smoothly, whereas on Windows 7 it was absolutley fine. I have upgraded my PC rather than a clean install as I have to much stuff on it and it would take a long time to get everything back! Games like pCars, Assetto Corsa, both rFactor's and even the older F1 games run fine, so does anyone know why it is just F1 2015? If it is purely because its not compatible with Windows 10, do I go back to Windows 7 (I have a month to decide) or stick it out with 10 and wait for updates to the OS? If going back to 7 is my only option I will do so. Cheers.
