So, I got a new computer and decided to try out GZDoom, since it didn't work on my old PC. However, as soon as I booted it up, the menu seemed a bit odd. So I pressed on into a level and there was so much flickering and missing textures it was completely unplayable. Any help? My msinfo and dxdiag are attached.

First make sure that your driver is really up to date. I have gotten a similar report about a year ago for comparable hardware, but that person never reported back after making the same suggestion. I have no information if he was able to solve it.
