I dono to paste here or windows 10 forum. so I paste here. Help me move if isnt applicable here

I have an old game last time i play on windows xp. it is in directx 9. now i have windows 10, i install and it is in directx 9 too. I use MSI afterburner and riva to see the directx version. The game graphics itself is quite bad for modern standard. How can i convert to directx 11 to make it nicer?

Simple answer: No, you can't convert DX9 games to DX11

can i download the latest directx11 files from MS and run the game as administrator?

Again. You can't. The game will still work on DX9. As the game engine is made for DX9
You can't convert DX9 games to DX11 unless the game developer themselves do something about it

That's it. End of story

May I know what your graphic card is?
Direct X is fixed according to the graphic card. If your graphic card is Dirext X 9, you can not change it to direct X 10.
Windows 10 is using direct X 9.

In simple word : NO, unless you willing to pump $$$ to game developer to remake it all over again.

hm i thought win10 running on dx12? Do you mean the windows will eventually follow the dx version of video card?

If you install Direct X 12, there are no problem because the specs can be downgrade compatible and you install your graphic card dx 9 version is also the same.
Only the new specs (dx 12) can not be used.

DirectX9 games should work with DirectX11. Direct X is an incremental dll meaning its always backward compatible. Eventually your current graphic card dictates which direct X features it can support up to. Either that or turn off hardware compatibility and run everything on software which is not a good idea. If your processor is not fast enough to emulate the features in software mode, it will drop it.

Old games that support older directX version will not look better with better directX version installed because they are simply not programmed at that time of development to make use of the newer features of directX (which does not exist that time).

So the original Diablo played with DirectX 5 will always look like the original Diablo played with DirectX 11 unless someone remake or remaster it.
