Blender starts fast then slows and hangs.

[Teoma]

I have a:

AMD 1538 MHz Processor
959 MB RAM
Radeon Xpress 200 Series SW TLL
Blender version 2.3 i believe (it's not the new one)

Blender starts fine but as it runs it gets slower and slower, until it hangs.
(almost like a memory leak....) I'm assuming it's an OpenGL problem with my video card but i don't know how to fix it. (it seems to slow more with extensive 2d usage- file saving, uv mapping, ect..) I tried putting the atioglxx.dll from the Catalyst 3.7 driver package in my blender directory, but then Blender gives me an error and won't start at all. Any ideas on how to fix it or what driver I need?

[z3r0_d]

have you tried the latest drivers?

this problem went away for me when I upgraded from 98 to xp... but I have a radeon 9600se

ATI cards have always had problems with rendering and preformance of the blender user interface.

The usual remedy is to install the latest set of drivers, and the problem should go away (as z3r0_d mentioned).

I've had the same problem (ATI Radeon Xpress 200M) and the driver trick didn't work either. Something that does work is to open the display icon in the control panel, go to the Settings tab, click on advanced, click on the Troubleshoot tab (might be different on other machines), and lower the hardware acceleration until it disables the Direct Draw and Direct 3D accelerations (on mine, it's the third setting from the left). After that, Blender works OK, and I only have to remember to set it back when I'm done. The only problem is that sometimes it will crash when zooming in/out of the UV/image editor.

Try this:
1. Download this file and put it in the same directory that blender.exe is in.
2. Set all graphics acceleration to maximum.

This will either crash the program upon start, or cause it to work smoothly. If it crashes, delete the dll. I hope for you it works smoothly, though.

Is that a newer version of the dll? It still makes mine crash.
