The lag is imperceptible, it's all in your head.
I speed run these games, I can easily identify when there is input lag. Thanks.
No, sadly not.
Have you tried the runahead feature that was added in RA 1.7.2? That had solved the very perceptible lag in several games for me.
Unless 1.7.2 is better at it than 1.7.3a, the run ahead feature causes lag where the game won't run at the full 60fps. The SNESC hardware isn't powerful enough to keep up with it from what I can tell.
I also noticed some strange "ghosting" effects when it's enabled, for lack of better term, when I used this feature on my computer. Which, for reference, is an 8700K with a GTX980Ti, so plenty of power.
Seems like some strange thing that it's processing a frame that you're not actually supposed to see because of the run ahead and ends up displaying both the wrong frame and the correct frame.
Again, I notice these types of things more than "most" people do, as I speed run these games. I like the idea and if it worked perfectly, it would be great, but the tiny microstutters or ghosting can be the difference in making a jump or performing a trick properly, which can cost a lot of time sometimes, so it just doesn't work for my purpose.
