Ok I have uploaded a new version that include comments as to where changes can be made.
Fog C-Script version

Still coded for A7 but I commented where changes need to be made for A6 users. (Only two changes need to be made.)

I had it running for around 20 minutes with no problems.
framerate was steady at 60 and that's with 50 entities.

After configuring my Graphics Driver proper I thought i'd recheck the framerate.
It now states an average of around 400fps with a max of around 750fps using the C-Script version.

All the best to you all.
