System Information
Windows 7 64-bit, 6 MB RAM
Nvidia Geforce 405 (newest driver as of today, same issue on previous driver)

Blender Version
Broken: 2.72.2 c8995ec (latest buildbot version)
Worked: (optional)

Short description of error

Sculpt is lagging severely with VBO´s enabled, but only after settings saved and restart. This took some time to figure out since I normally have a lot of customized settings.This has worked fine on same system before.

Exact steps for others to reproduce the error

Start Blender with factory settings
Activate VBO´s in user setting and save
Add UV-sphere
Add multires modifier, subdivide to about 1 mil polygons
Sculpt (smooth and fine)
Exit Blender
Restart Blender
Redo steps 3-5 (laggy performance)
Reset factory settings and redo steps 2-5 (smooth and fine again)

No other settings but VBOs were changed, except that I enabled fast navigate in sculpt panel.

Can't confirm on Linux (GTX 570). Will check later again on Windows

Indeed, running dualboot and tried in Ubuntu. No issue there.

Those are OpenGL drivers issue, it is a known fact in some cases VBOs will be slower than no VBOs (not logical, but...). We cannot do much here, actually. Thanks for the report, anyway.
