If you start darkplaces.exe directly you will end up inside OpenQuartz.
In the main menu, simply start a new singleplayer name, or go into the console via pressing ESC inside the menu, then type map start and press Enter.
To access the console inside the game, press ^.

To edit any settings please edit the autoexec.cfg inside the /darkrevelations folder, it also includes descriptions for the contained settings.

At this state this game is heavily commandline dependent, f or documentation on commandline/cfg parameters take a look in the /docs folder inside of X:/installpath/katharsis/darkrevlations folder.

Thanks for the feedback, i will help you as good as possible!

I suspect Crossfire to be responsible or the bad performance, else your machine should run it just fine!

Please try this and tell me if it helped:

Best Greetings

Hum, Thanks for the suggestion but even with crossfire disabled performance is still very bad, do you have a Nvidia GPU, what is your fps's when looking to the center of the room? It could certainly be a combination of an AMD OpengL driver problem with your game, plus the fact that you have, imo, to many shadow casting lights, visible at the same time when we look to the center of the room, i counted a total of 6 that is overkill, for example when i look to the corners where you have a single light, performance jumps considerably from 8 fps's to more than 40 fps's. Please don't take this wrong but you should not have more than 4 shadow casting lights visible per frame, you should also be careful with overlapping light volumes, i know this because i'm modding the idtech 4 engine and this engine is very similar, if you enable the r_showoverdraw command and look to the center you will see what i mean.

By browsing the forum link that you gave me for AMD and darkplaces problems something came to my attention, it seems the water maybe the culprit here, in the forum they say the "pretty water" on darkplaces rapes AMD cards. And you have a small water pool in the exact place that is causing the extremely bad performance for me.

Interesting, you can test that by opening the console with ^ (~ on US keyboards) and typing in r_water 0.
That turns of pretty water.

If that doesnt help, you can also try to replace the Darkplaces Engine by the latest stable release, as i used a development or this release:

sorry for the extremely late reply but i was very busy and then forgot about this, did what you said and the performance jump was considerable so yes the "pretty water" is to blame here.

You should create a thread for this mod at the QuakeOne forums, a lot of people there use the DP engine and they might be able to give you more feedback running your alpha with different hardware.
