dxdiag says I have directx 12 installed. But some video games I want to play use directx 8 and 9 and the cd rom comes with the directx installer for the old versions. But if it did get installed, how do I check if the old versions have been installed?
Hello, this is kind of a pain to have to post this, but recently i had to reinstall windows, about 2 weeks ago since i got a new NvME SSD, and a Samsung 1TB SSD, so i installed my boot drive and installed Windows 11 from my old SSD, fast foward to getting everything installed, i wanted to play Hell Let Loose and Kenshi, but DirectX will not work for either, for Kenshi, it plays but has 0 audio. and for Hell Let Loose, it just wont play at all. But every other game seems to work just fine, which is super confusing. before reintalling Windows to my new SSD, i never had an issue with it. Now it seems i cannot get it to work whats so ever. Ive tried every fix from YouTube, everything on the first pages on Google, all of that. Ive factory reset my PC twice, and still nothing works. Heres the logs if anyone can help: DXError.logDirectX.log

I think this example is fantastic as is. It just needs some adjusting specifically when someone wants to use a VM for development as the VM and host become unresponsive, however on a native machine it runs great. I've already used this example to help me make a basic window, which was really difficult for me to understand. As a mac/Linux programmer the way windows does it's references and com is a challenge for me and this example really helped me begin to grasp that stuff.
if you would have graphics card with 'hardware windows acceleration' then you can try to compare it by performance.I'd see once one had mentioned in 90's.Despite not cost-effective maybe it may accupy some share.But gdi has no even basic 2d stuff like alfa channel or swap buffers(despite its 'doublebuffer' in window class).
I manually downloaded and extracted VMware Tools for Windows from anil2016's link (replacing the copy of windows.iso that was in the VMware Workstation folder), and after that I was able to use the Update VMware Tools option in the VM menu and confirmed it had DirectX 11 support.
I hooked the frame presentation logic from a pre-existing direct3d/directdraw wrapper to
a custom delay function that ties to the precise timer that windows provides in QueryPerformanceCounter()
even windows 9x appears to use the pentium's time stamp counter under the hood,
which is more than enough accuracy for a 1-60 fps target!
