OpenGL on Ubuntu -> Dynamic Lights look bad

[TourianTourist]

So, I'm running UT99 on a ThinkPad with Ubuntu 18.04 installed, using Loki and its provided OpenGl renderers. It works fine for the most part, but dynamic lights look quite horrible, as if they were rendered in tiles. See the attached screenshot for how Pulse Gun shots look like...

These are my current UnrealTournament.ini settings concerning the rendering stuff:

Anybody knows which boxes I need to check to fix this?

I would just wait for the Linux 469 build to come out, I was using opengl on Ubuntu with the 469 build at it worked perfectly, Or you could ask to join the beta testers here: https://www.oldunreal.com/cgi-bin/yabb2 ... 1569587267

This could be due to the low resolution of lightmaps.

This could be due to the low resolution of lightmaps.

Okay, and how do I increase those?

This cannot be solved by editing the config, you will need to make changes to the map.

It's not a map issue. It looks like this in the entire game (it's only more notable on dark maps) and playing the same map on my Windows PC looks completely fine.
