went back to 6.99 on my cabinet with newest nvdia drivers...speedy again but of course no videos,, rolled back nvidia driver from a few months ago and all is well.
Tested 7.02 with newest nvdia drivers on my main pc setup,, I only have 10 or so tables installed and only 1 has a video....when I scroll between tables with no video everything is fast, when I get to the one table with a video everything goes slow until the video I navagate to a table with no video.
So it looks likes vidoes/video player cause slow down pinballx greatly on 7.02, I had a feeling this would be tricky, thanks to Tom in advance, I know eventually he will get it right and I encourage people to contribute to him for this free software!
I might try to see if newer videos created with version 7.02 do not cause slowdown when I get some time.
