Things are moving at Codemasters
Not that I know of, still very arcade/unrealistic physics. Actually plays better with a gamepad than a wheel.
Thank you for submitting your recent request to Codemasters Customer Services concerning Grid Autosport.
This version of the game does not officially support Windows 10, so we are limited in the support we can provide unfortunately. However as long as all your hardware has Windows 10 compatible drivers, and meets or exceeeds the minimum requirements of the game, you should be able to get it to run. We also recommend verifying the integrity of the game cache as detailed on the following link:

We have no plans for a Windows 10 patch, at the current time I'm afraid.
Kind regards
