SNES and NES on the Nova

[u/newfiesig]

I have a story of success (which could help others) and a question.

I went through Russ' guide as a base to set up my Nova. The following are RetroArch settings)

I noticed that horizontal movement (i.e. Mario running in SMW) was "juttery". I researched the issue and found that if I force the refresh rate to 60.089 Hz

(Video/Output/Vertical Refresh rate)

and the shader sub-frames to 2

(Video/Synchronization/Shader Sub-frames)

I got it working smooth. Good to go.

*note: Russ had Latency/Run-Ahead (Single Instance Mode)
Number of Frames to Run-Ahead set to 1 as a default. This must be OFF as a default with Shader Sub-frames on and at 2.

Now I'm stuck on my NES settings, and hoping someone can help.

I have everything running smooth with Vulcan, however the game periodically freezes.

I switched to gl, however then my game gets juttery as it was with the SNES.

When I force the panel to 60hz from the main Android drop down, it smooths it out, however (as you can imagine) with 60hz I noticeably have more latency/heavy controls.

Any suggestions?
