So I've got one machine with pretty bad mouse/sprite lagging. It starts when Ethereum mining starts. This machine was working fine and I had to rebuild it with a fresh Windows 10 install.

It's Windows 10, latest, all patches. ULPS is off, I have never used ethi so not thinking I need to start now.  I did try ethi 1 and the hash rate dropped significantly and still lagging. Visual effects in Win 10 are off.  I've tried everything I can think of and could use some ideas.  GEForce software isn't installed (or at least I don't see it anyplace).  Mix of RX580 cards and a couple of GTX 1060's. Radeon driver is the recent .5.1 and Nvidia is the latest one.

Help!

Thanks,
CJ
