So I can give you an update now.

With a small sturggle to get my update the version you told me to do, I managed it.
And for now, even after running alphascape v2 i had none FPS drops. Of course with Direct X9 and low laptopt graphics in FF. But that doesnt matter, I would take stable and smooth frames over graphics any day!

It works for now really well! I just hope it stays since the last time I was thining it worked, was for 2 hours and then the drops kicked in.

I will update you when it happens again!
