I just played Super Ghouls 'n Ghosts on Switch. It was nice, I thought. Then I played Super Ghouls 'n Ghosts on my SNES console and a CRT and thought.... wooooooaaaah! The controls are so direct and precise!!! The same with Super Mario World. In Super Tennis it was hard to even get one ball, although I played the game 50+ hours. I only have 20ms input lag in game mode on my flat TV, but the emulator on Switch seems to add quite a lot lag...
The games, which are emulating the Super FX chip (Star Fox, Yoshi's Island), don't even run properly with only a few frames per second. That's ridiculous.
Well, it's better than nothing, but far away from a real SNES experience...
That's... not true. The only ones that run poorly are Star Fox and Stunt Race FX... But those always ran bad to begin with.
Indeed both of those games (stunt race especially) dip down to the 10-15fps mark when stuff gets busy and really in emulation you can't up that frame rate because those games logic were tied to the framerate so if you make them smooth they become super fast. You can see videos on youtube of OC'd Super FX chips and it looks nice but borderline unplayable because of the speed.
Stage starts at the 3 minute mark. Realistically the extra frames of animation just aren't there from the CPU for the GPU (Super FX) to draw so all that happens is the CPU chucks out the frames it would have drawn anyway but at a rate to make up 60 of them per second, the end result is something which is 60fps but... just not at all playable.
It would be like trying to make a 24fps movie into a 60fps movie by showing those frames at 2.45x the speed they were meant to be displayed, it will result in a smooth 60fps film... but it will also sound like the chipmonks.
