PrBoom Filter Options

Recommended Posts

I had a quick question about some of the PrBoom options. Specifically under "Renderer Settings," what do the different options do? I understand that they're texture filters, but would "Point" be the most Doom-Like while Rounded would be the highest quality? Or what? Sorry for a relatively uninformed question, and thank you for any answers.

Point is basically "none", it doesn't do anything special.

Linear is, I think, OpenGL mode style bilinear filtering in software mode. To my untrained eye it certainly looks like that blurriness I see in OpenGL mode screenshots, anyway. It works better if you do it in a high or true colour video mode, 8bit doesn't cut it.

Rounded apparently just tries to compensate for the huge blocky pixels effect when you're stood close to something by rounding the corners of the blocks. Unlike linear, I don't think it does any colour interpolation.

Not sure if complevel applies to these visual things, but if you don't already know and if you want doom2 behavior/ or boom etc, you don't have to mess with all the individual options (like lost soul limit etc). Instead go to your prboom.cfg file (open with notepad) and change the line
default_compatibility_level -1
from -1 to whichever compatibility level you want (like 9 is boom and I have mine set to 9.. for the rest see readme.compat.txt in the zipped included prboom-docs folder). Apparently this default overrides the menu options. Just mentioning because doesn't seem intuitive to me and I didn't know earlier.

OpenGL settings aren't affected by compatibility settings.
