I'm hoping it gets fixed in the next release / update of GSU. It's one of the most annoying things about GSU. I seriously don't know why this is still a bug, surely there is more than one way to fix this.
Some other things I'd like to see in the next GSU release / update:
high poly / large model support
modern hardware support (specifically multi core CPU's)
lighting issue seems to have been resolved by people developing a plug-in ATM
bump mapping
jolts between scenes when exporting an animation
I'm sure there are some more things, but these (the above) are the ones that come to mind first.
