Glad to hear that.

Something is up.

Interesting. This is what I meant when I said that trusting rendering times alone isn't always telling the whole truth. However, 6233638 also has better real life performance with the option enabled compared to having it disabled. So it once again seems like the option behaves differently for different setups. Anyway, I'll disable it by default in the next build.

I think this was reported by other Windows 8 users before. It doesn't seem to occur on Windows 7. You could create a debug log for me to check if I can see anything wrong. But IIRC last time I checked, madVR behaved correctly. I think it's probably a driver problem. I think that either the driver is telling madVR that the original mode was 59Hz. Or alternatively, when madVR asks the OS/driver to switch to 60Hz, the driver switches to 59Hz instead. One of those 2 things, I think.

That's not as easy as it may sound. Performance depends on so many factors. E.g. I've found that on my PC Jinc scaling is relatively fast with very small scaling factors, but gets exponentionally slower with bigger scaling factors. Also the anti-ringing filter is so much slower on older generation GPUs than it is on newer generation GPUs. Finally, with v0.85.5 I just introduced special shader code for 2x and 3x scaling factors, which is way faster than with other scaling factors. How could I possibly show such effects with one simple graph?
