MM8BDM no longer playable in OpenGL?
« on: March 24, 2017, 12:30:25 AM »
Until now, Zandronum has been running quite fine on my Windows Tablet, in OpenGL mode. But now, it's completely and suddenly unplayable. I'm getting complete lag spikes even from the menu screens, and sometimes I have to force close the game with Task Manager. I never updated Zandronum, so I don't know what's going on here. :(

Software mode still works fine, though.

This has been a noted issue on Windows 10. The windows update you installed reverted your integrated graphics drivers. You must reinstall those drivers from your manufacturer.

I had a similar issue too. Now I'm on Windows 10, so ya can take that part to the bank or somethin'...
Anywho, my resolution to my problem was to uninstall a security update that happen'd to me around 2017/03/14~18.

Here's how to do it:
1. Go to the Taskbar and hit the Start Menu.
2. Go to Settin's (Looks like a cogwheel).
3. Hit Updates & Security.
4. Hit Update History.
5. Hit Uninstall Updates.
6. Find the Security Update under the "Microsoft Windows" section for a Security Update for Microsoft Windows. It should be around the date that I mention'd above.
7. Right click and uninstall it. Ya WILL need to restart yar computer afterwards. Afterwards, ya done!

Hopefully after that, ya should be able to run OpenGL again. If not, then ya might have to dive into deeper potential problems like actual degrade'd graphic drivers and so on, which is quite the nightmare in itself.
