SEVERE framerate problems in certain wads

Post by ETPC »

Heya.

Recently, I've been having a lot of problems with speed and framerate in some wads. High-detail wads such as UTNT, COTD:A and CAH among others run at poor framerates. This is pretty weird, seeing how the reason I stopped using ZDoom and moved completely to GZDoom originally was for this exact reason, albeit it was a lot worse on software (hard-locking the system in Hexen randomly).

My specs aren't that great (upgrading soon :D ), but I see no reason as to why I can't play these wads:

Intel Pentium D 2.80GHz
GeForce 8800GT 512MB
4GB of DDR2
Windows XP Pro
On-Board Sound

I also have the latest drivers for my video card and I am using the latest SVN build for GZDoom (1.2.1.321). I run at 1680x1050 with most GL features on and if needed I can give the exact settings. Speaking of which, is there a tweak guide that can tell me what does what in the OpenGL menu? I have no idea if some of these options are useful in the least for most wads.

Any bit of advice would help. Thanks in advance.

Certain constructs will have performance issues. All the maps you list are among those which are known to cause problems.

The biggest performance killer is to use multiple stencil based portals recursively (e.g. horizons in a skybox.) Reflective floors that reflect the contents of a skybox with a horizon line are particularly nasty and I know that CaH contains some of those.

But isn't your CPU a little underpowered for the graphics card you use?

The wonderful world of OEM's. I was a damn fool :(

Yeah, I'm gonna be getting a i7 soon.

So is there anything I can do? Any options that would help, tweaks, etc?

Also, apologies for posting this at ZDoom as well. I need as much help as I can get.
