[engine limitation] Portals

[Tomcat]

Portals often do not show correctly in software. Their lower sectors look unclosed when you look at portals from specified angles.

My config is: Duron 800, Trident Cyberblade 8M. But all my friends encountered this problem too.

This is a known limitation of ZDoom's software renderer. Since this is outside GZDoom's scope I can't do anything about it.
