I have a pretty large project about 1GB, 4 scenes and recently Blender has become too slow too use. A couple of annoying things, other than just lagging are:. I have tweaked my GPU settings several times and used this project on Windows and Linux dual boot and see the same problems on each. Is there any sort of performance monitor or profiling that would be able to say what part of the project is running so slowly?

Another guess would be that it could be an issue with the hardware. Perhaps the CPU is having a hard time because of the number of cores? Another possible theory is that there are other programs in the background taking up all of the extra resources to speed things along. Another possibility is that the number of vertices in the scene is high that it lags. You may have to, as neighborlee suggested, to do something to reduce the high poly count.

Blender has been lagging heavily since a recent upgrade, although I cannot say exactly when because I didn't use it since march or april. Basically, there is a seconds lag everytime I select an object or try to move it, and it doesn't just happen in complex scenes but the simple start scene with a cube, so it makes it absolutely unusable.

The lag time seems to be proportionnal to the size of the window. I use blender quite a lot in the past year and never encountered such an issue before. What's more, the bug is retroactive for pretty much all anterior versions of blender that I tested, and I went back as far as version, so I guess it's pretty safe to say the problem doesn't come directly from blender, however I have a few other 3D applications that still work well.

Something interesting to note is that the nightly builds of blender 2.
