Yeah, I guess that confirms it's real performance issues on some games for me, since upscaling even to 2x makes them worse in those instances (yet in other games it suffers if I go to 8x, anything less they're good). I don't really care to use graphics enhancements outside CRT shaders but nice to know all that about what each setting does, AA and all that stuff. Oh well, maybe they'll improve, or I'll get to upgrade. Conker so far is the worst performing game and it even froze (not RA, just the game) during the intro. I also notice some glitches in GoldenEye, the snow level with the radar, there's some weird clipping with the mountain background visible through some of the tower rails and similar. I dunno if that's the emulation or the game. There was also a spot in OoT around the Death Mountain Trail where the floor became invisible and through that it looked like no-clipping but that was before I switched to the correct plugin so I dunno.
Edit: wops, vsync off (I thought maybe it's different for me cos I've been using g-sync-c) and framerate set to original appears to have fixed performance in N64 games, I can even increase upscaling in most (though again I don't really care about that stuff, in Perfect Dark it still has performance issues above 1x when using the night vision, spy camera etc. with the high-res mode). Conker still froze after a while of playing though (and what a horrid framerate it has natively).
This kinda sucks because (in my setup?) vsync needs to be on, otherwise games that run at 60fps, even though the emulation speed is correct, the audio doesn't distort, etc., they look 30fps visually. Setting it to off as a core override for Parallel alone doesn't actually work properly either, so just for this core I have to set the global vsync to off, then set core overrides for all the others with it set to on. I also can't switch between other cores and Parallel during gameplay or the global setting still doesn't apply right for it, I have to first close the other core's game I'm playing (thankfully not all of RA) then load a Parallel game.
The existence of 60fps N64 games like F-Zero X complicates this further. Thankfully at least that game (I don't know about the other 60fps N64 games yet) doesn't actually get performance issues with vsync on like the games I mentioned earlier so I can turn it on for it. Given the peculiar behavior where changes to vsync settings don't apply quite right in Parallel a game specific override doesn't let it work in this case either however. So the process I found that works is to basically first load F-Zero X with the same global vsync off setting, then manually change it to on and it does apply and the game looks/plays all proper, then before closing the game I have to manually change the vsync back to maintain the above behaviours as without functional overrides it's the global setting.
Oh well, figured out all (?) the quirks at last, hopefully core/RA updates get rid of all these things though, vsync shouldn't have such an effect on any of these!
I've yet to try properly setting up a n64 emu (or core in RA), but has anyone tried emulating the Wii VC version of OoT?

I've not tried but they should all work fine. I've tried an arcade VC rom before (Wonder Boy in Monster Land for its English text) in FBNeo and it worked normally.
