No problem - glad it worked - never know! It’s so variable and everyone has different experience.
Another thing that has really helped me is turning off the Nvidia Background App Frame Limit (I had it at 30 before, which I did by following one of the good setup videos – so no idea why that was suggested) and also using Riva Tuner to lock the FPS to half refresh (if you are using SSW / MR) as I found this so much smoother and better at capping than NV equivalent. And for some reason even though the SSW should have been doing the cap, it was but not as solidly. Riva really makes everything fluid in most situations now.
Man, so many settings - I have been back through everything and hopefully, finally, looks like I have cracked the Goldilocks zone. We shall see! Looks like SU15 is actually going to help though unless they break it / make it worse before public release. I’m sure they are quite capable of that!
