I ran a scan and nothing showed up. I'll email you the system info.
Just to mention it, I haven't experienced the problem since, but I'm still none the wiser. I did get to the last levels though, it really kicks off!
I don't know too much of what goes on behind the screen, but here goes:
xin 10 home, 64bit
intel core i5-3230m, 2.6ghz
8gb ram
nvidia Geforcre GT750M, 6087 mb
1920x1080 60hz
its a lenovo laptop
Yeah it is weird, it seems like it happens pretty sudden the shift to slow...
thanks for the answer and the promising game:)
