i want know what are the options for have less lag fps in ogl, i run fine basic wads and mods but like aow or huge maps i have low fps (10-20) so what are the better options for have more fps? or how i can have more?

hmm
resolution 800x600 or 1024x768
rendering quality:speed
vertical sync:off
sector light mode:dark
fog mode: off
fake contrast:off
particle style:square

on shader options all off:
texture options -> texture filter mode:none, antitropic filter:off, high quality resize mode:off

Most of things´ll run better with this

edit: on console
gl_fog_shader true
it may help you :)

thanks ibm! now i feel it more smooth :)

This helped a LOT. My FPS in GL jumped from 20 to ~100 on classic maps.

Do shaders have the effect of looking prettier or accelerating the drawing of their respective elements? I was never sure whether I should turn them all on or off to reach the best performance.

one question, what does the gl_fog shader ?

you also could use RGBA2 instead of RGBA4 this helps too, or if you REALY don't care about visuals you could use COMPR_RGBA which makes the textures look like garbage in some cases. it didn't on my old pc thou.

Prettier I believe, though I can't be sure. The visual difference is - at least on my end - negligible, as is the performance diff.

I'd suggest keeping on Shaders for Texture Warp, otherwise expect some major lag on higher res textures that have warps. (128x128, and above.)

If you're not running any WADs/PK3s with any large warping textures, depending on your card, you *might* get higher performance with it off, but I'm unsure.

Kind of depends on your video card. If your card's shader performance is decent, you might be better off leaving all shaders ON, as they'll likely be more efficient.
