Help me

Does this happen to anyone else?

-Setting resolution above 640x680 causes massive slowdown
-Setting depth higher than 16-bit causes massive slowdown
-ZdoomGL starts up at 8-bit color depth
-Monsters appear invisible when you exit the room that they are in.

ZdoomGL looks very nice, but I have alot of problems (could someone help me possibly resolve theese problems?)

hmmm... What kind of machean are you running it on? aside from your last point, I have encountered none of these problems.

but in regards to your last point, "-Monsters appear invisible when you exit the room that they are in." That is a bug in ZdoomGL wich will (hopefully) be corrected in the new relese... come on timme!! :P

try reading the FAQ in regards to your other questions...

The third one can be fixed by editing the zdoom.cfg file and setting vid_bpp (or vid_bitdepth) to 16 or 32. As for the top 2, it's probably because you have an old machine or video card.

Computer Specs:
-1.5Ghz Pentium 4
-Nvidia TNT2 Video Card
-128Mb Of Ram
-Sound Blaster Live x-Gamer 5.1 Sound Card

"-Nvidia TNT2 Video Card"

There's your slowdown ;)

Yeah, I hear that from alot of people whne I say I have a speed problem with some games. Looks like Im gonna have to buy a new card, since alot of games run slow because of it. Any recommendations?

One word. GeForce. ;)
