How do I disable hardware acceleration on the latest version of Window

did you ever find a solution to this? Im having a similar issue with some of my capture software and i think that may be the issue.

Like you my tab is missing so had to resort to adding DisableHWAcceleration as a DWORD with a value of 1 to disable HW acceleration under HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics

it seems it didnt help me, but feel free to try it.

The problem stopped with no action on my part (I rebooted my PC). However, I expect it to come up again and I'll contact TechSmith when it does. They are the ones who told me about hardware acceleration being turned off in the first place. The problem is: I can no longer turn off hardware acceleration with the latest version of Windows 10. That isn't an option any longer.
