How to run older Windows versions and DX9 games on both Windows 10 and Windows 7?
How to run older Windows versions and DX9 games on both Windows 10 and Windows 7?
I compared the performance using the same computer with both Windows 7 and Windows 10. The results showed that Windows 7 performed better by 5 frames per second, while Windows 10 was faster by 5 fps for ETS2. There seems to be a possibility of adjusting settings to run older games on Windows 10 as well.
Maybe consider this alternative approach;

There seems to be no solution when I turn off the DX11 setting in the Graphics section—it only works with DirectX 11.

Make a game run a specific DirectX version / Direct3D setup
For instance, if your game operates in DirectX 11 but supports older versions, there’s no manual way to adjust? No worries, there’s an easy method to lock in a certain DirectX edition for your outdated graphics card. Begin by going to Settings ->...

I hope this assists.
Thank you, Lutnj, but these are intended for dx11 games to operate in dx9. What I really require is a native Dx9 application that functions smoothly in Win 10, just like it does on Windows 7.
Are you employing identical driver versions across both operating systems?
It might simply be because mafia2 operates as a 32-bit application, performing optimally on the 32-bit version of Windows 7, whereas the other title is built for 64-bit and functions more effectively on the 64-bit edition of Windows 11.
I have drivers from AMD's official site, and I installed drivers for their respective operating systems (one for Win7 and another for Win10). Also, I'm considering your opinion regarding the OS architecture for each game. Mafia 2 was released in 2010, whereas this ETS2 version is from 2020.
It might be due to additional background processes or increased driver demands for specific tasks. However, I'd like to clarify the comparison point—what exactly are you aiming for? If you're seeing around 200 frames per second on Windows 7, a drop to 5 FPS would be quite significant and not ideal. A reduction closer to 40-50 FPS would make more sense in that context.
But it might also be due to variations in the driver versions for Windows 7 and 10.
In reality, I'm achieving around 55 frames per second with Mafia 2 and approximately 65 fps in ETS2—both consistently across both Windows 7 and Windows 10. In terms of exact figures, 55 fps on Windows 7 and 51 on Windows 10 (for Mafia 2), and 70 fps on Windows 7 and 75 fps on Windows 10 (for ETS2).
