Previously Blender worked perfectly for me, rarely any slowdown unless there’s an absurdly high amount of vertices or something. Due to a massive computer issue, I had to reinstall Windows 8.1 entirely, and lost everything that wasn’t backed up.
I reinstalled Blender 2.49b (the version I use), Python 2.6.2, and my graphics card’s latest drivers (Radeon, latest 14.12 Omega version of the drivers). As stated, previously I had no issues. Now every single time I enter Object or Edit modes, I get some serious slowdown/jerking, but Texture Paint doesn’t slowdown at all.
What could be causing this? It’s making Blender nearly unusable, and considering I often worked with Blender maybe 4 hours a day as a hobby for a very long time now, this is a pretty bad problem. :no:
EDIT: Upon further investigating, I found that if I use Blender right after turning on my computer, sometimes it runs silky smooth again, but othertimes it doesn’t. This is really frustrating me.
EDIT 2: After further investigating, I found that changing OpenGL “Wait for verticle Refresh” options briefly fixes the problem. It runs silky smooth again for about 10 seconds, then starts jerking a lot again. I change the Wait for Verticle Refresh again, and 10 seconds of smooth then jerkiness again follow.
I know my graphics card is not about to break or anything, because every other 3d program I run on it (DirectX or OpenGL, doesn’t matter) runs perfectly fine.
