Actually, I was thinking of each texcoord calculation step. Actual drawing would be much faster since that's all handled on C side.

I had to tear down one of my private addons because I was doing literally hundreds of vector calculations and in raid, it bogged my computer down a lot even with that as the only code running. I have a new version of my vector library built for a new iteration of the addon, but it's far from completed to the point where I can stress test it.

Nah, still using XPerl :p - I did try ZPerl, but there seemed to be some issues with saving settings between characters, and copying settings from other characters. Since XPerl still works fine for me, I switched back for the time being.

Hmm i experinced no issues like that.
