I've tried blender 248 on several machines over the past several months. My laptop, my home desk top (3.0 Ghz, 2Mg ram), even an apple iMac (2.4 Ghz quad core 4 Mb RAM) and I find the blender interface to be really slow.

When I click on buttons I have to wait between 5 and 10 seconds for anything to happen. It should be instantaneous. Example, if I want to move an object I click G (grab) and then move the mouse. 10 seconds later the object will eventually move to the desired location but in a slow and choppy manner.

Is anyone else experiencing this? Is there a setting I must set to get Blender to react more like other programs?

very strange, works ok for me several different machines from a sempron 2400 upwards, win 2k on that box, ok on xp on 1.5G duo lappy too.

Toolset: Blender, GIMP, Indigo Render, LuxRender, TopMod, Knotplot, Ivy Gen, Plant Studio.

That sounds like when I tried to run it on an ATI card using OpenGL I believe.  Scrolling over menu options popped up really slow.

I believe there's a list of various supported Graphics cards / Drivers on the Blender web site.

ATI have had weak OpenGL for years :(, shame because when it works the visual quality is superb from ATI cards, but let down pretty much by a poor driver :(

I find it really snappy when I first open Blender, but as I work it gets slower and slower to the point it being unusable. I then must restart Blender. I don't believe all the machines I've tried it on have ATI cards but I'll check.

My home desktop has ATI Radeon and lappy has an ATI Xpress 200M. The machines here at school are quad core iMacs but I don't know the graphics cards. Most likely ATI aswell as Mac has largely used ATI in the past.

I'm getting the same thing in 2.48 - Vista 64Bit, dual AMD 9550, 32 GB RAM, nVidia 280 video card.

Just for a comparison I've  tried 2.43, 2.44, 2.46 & 2.47 on the same machine and all are blazing fast. I can sculpt at literally twice the resolution in 2.47 as in 2.48 before I hit the performance wall. Seems to be a definite memory usage problem in 2.48 from what I'm seeing.

works fine here, probably an opengl thing, what worked for me when i had an ati card was download an optimised version from graphical.org, some how it made the graphics card work better too. so check versions made with diffrent compilers.

for some free stuff i made
and for almost daily fotos

I don'r really want to fool with my graphics drivers. I also use Max and I've got my vid card working with Max after much fiddling.

But I'm glad I'm not alone. At least there seems to be a consensus on what the issue is.

I highly recommend updating to the latest drivers.

I also recommend nVidia, but hey thats probably personal preference. I seriously doubt one is "prettier" than the other, its all about the speed that the card can render the prettiness. :)
