serious lag issues

[tesla]

I think ever since I switched to Windows 10 I have been getting serious lag issues when playing games on the 4DO. I was running fine on Windows 8, although I was using an older version on 4DO.

Try the last version of 4DO.
I also have Windows 10, but no problems with playing.
I had a problem with the launch when I installed 4DO to a folder "Program files", try to put on drive "C:" - C://4DO/, maybe this helps.

I have switched back to Windows 8 and I am still having lag issues, but not as much...
