DF Runs inexplicably slow on my new graphics card.
« on: July 31, 2008, 06:45:39 am »
I ran DF on my radeon x1950 pro just fine through many versions but when i installed my new geforce 9600gt it started running ridiculously slow. The intro movie crawls along and the game gets like 5fps unless i set gfps cap to 10, then i get like 26fps on a small site with just the 7 starting dwarves. i have tried many different sites but either way, even th intro movie and main menu are slow and laggy. Weirder still, it gets worse when i use higher resolutions like its straining my card or something.

Did you get the latest nVidia drivers?

aye, i have the latest drivers. I've turned off/on vsync in the DF ini and in my nvidia control panel. I've turned music off. I even swore a blood oath to Armok. I cant imagine that DF is straining my card and my old card was slower and it ran fine. I'm totally lost here. I've uninstalled all ATI drivers via control panel and with Driver Sweep. I'm running XP, nothing changed from when i was getting normal fps to now other than the video card. I've also tried old versions that i know ran fine and they are just as slow as the new versions with enhanced world history gen.

Well i dont think its a issue with DF.

DF uses SDL im pretty sure.

So if anything its a problem with SDL.

One thing you might try is turn off 32bit graphic mode in display properties and set it to 16bit.

32bit runs much slower then 16bit.

Just a shot...  Get Rivatuner and try fiddling with the OpenGL settings.  The "intellisample" section is what caused the problem in the past.  NVidia drivers have a history of causing mayhem in DF mostly corrupted text/tiles but who knows.  And unfortunately trying to manipulate the same settings in the regular NVidia control panel never worked for me I could only fix it with Rivatuner.

I have the same graphics card and DF runs just fine. My current for is around 40 dwarves and still running at my max FPS of 120.

well i'll be damned. there were some remnant "asus enhanced display drivers" seperate from catalyst drivers. removed those and started DF and it went as fast as can be. Thanks for the replies folks.
