Ubuntu 18.04 GZDoom Software slowdown

Recommended Posts

Posted (edited)

Hey guys, recently switched from Windows to Ubuntu 18.04 LTS and I’m getting sub 60 FPS performance in E1M1 with the software renderer. I’ve sudo apt updated and upgraded so I think my graphics drivers are up to date. When I had windows I never got less than 60 FPS in E1M1 in software mode. 


Running Ubuntu 18.04 LTS with an Intel UHD 620 and an i3-8130U running GZDoom fullscreen 1080p while plugged in. Its not a screamer laptop but it never ran this poorly with windows. Is there anything I can do to prove performance? I presume Intel’s lazy and that they’ve been neglecting their open source drivers.
