These splashes will be getting some tweaks. Their positional changes are mostly done in PostRender(). The problem with this twofold:
A. Can be jerky
B. Speeds can be twice as fast as intended on some operating systems.

I will be moving the code to Timer().

I have finished one already, the matrix one. It did need the above changes, plus I redid the logic that was specific to it. It is now way, way smoother than it was.

Here's what it is supposed to look like!

Well let's go through the checklist. We have the same screen resolution. You said you had high World Texture Detail? How about what is your:
Color Depth, 16 or 32 bit?
Video Driver, OpenGL or D3D?

Actually, this reminds me of a problem I had with the game intro splash another post. I'll just copy that fix here:

[OpenGLDrv.OpenGLRenderDevice]
UseS3TC=True

(that's in the your UnrealTournament.ini file)

Let me know how it goes.

The font is fixed width yes, it is Courier New, size 14. I don't think it is the greatest looking font but I needed something fixed width to make life easier when making the texture.

I'm going to change the coding to be based on a 256x256 tetxure. There won't be as much variety but I can't have everybody trying to tweak their settings just to see the matrix properly.
