Just like in the old days, it is the modern features that suction the power.
Reduce the demands on your OpenGL video by keeping 3D window views tiny. Minimize OpenGL options - dialog 'Options' in 3D Window Settings.
Select simplified Redraw options in Work Environment. [mine are attached, but experiment for yourself]
Speculative savings:
Keep Info box showing minimal data - set this for each tool in Work Environment.
OR: Learn how to work without the Info box entirely [lots of systematic favorites and eyedropper use can help]
Turn off extras like Tracker and guide lines. Animated zooming hahaha!
Eliminate fill options from your views to speed redraw.
Think about how to reduce the number of layers in the view for rebuilding speed.
