I have made a quick check using the same computer with both Windows 7 and Windows 10 running Mafia 2 (DX9) and ETS2 (DX11). The simple answer is that on this PC, Windows 7 runs Mafia 2 about five frames per second faster than Windows 10. But wait, Windows 10 actually makes ETS2 run a bit quicker by five frames per second compared to the old version. Is there any way to make Windows 10 play these older games as smoothly as they did on older computers? PS: I tried putting Mafia 2 in compatibility mode just for Win 10 but it didn't help at all. Thanks so much for reading my message!

Here is a simple guide on how to play the game in DirectX 9 mode on Windows 10: If you don't see anything happen when you turn off the DX11 setting, then it means the game is only running in DirectX 11. You can force your old graphics card to run specifically for DirectX 9 by going to Settings and clicking on Steam Community or this link at https://inxile.zendesk.com/hc/en-us/arti...-9-Windows. Hope this helps!
