Please allow .5 and .75 Rendering Resolution #19247

Closed slrgt closed 3 months ago

What should happen

I've been playing PSP games on the RG35XXH and a lot of games run great on it. Monster hunter runs almost perfectly but some games like Ratchet and Clank run very laggy. Ratchet and clank is much more high textured than monster hunter so I would like to downscale it to .5 or .75 rendering resolution so it can run better.

Who would this benefit

Increase performance of games.

It's unlikely that lowering the resolution below 1x will actually improve performance, unless you're on some very underpowered hardware, which probably will have other performance issues anyway. What device are you playing on?

Im playing on the RG35XXH its not very powerful and the screen is small enough that lowering the resolution wont be noticeable, monster hunter runs great so i think lowering the resolution on ratchet and clank will be enough to get it running smoothly.

Got one of those cheap "retro" handhelds for a kid, and can tell, they are only good for what their name suggests, up to PS1 emulation(and that without any enhancements) anything more and not only battery life stops being a thing, the experience turns subpar compared to just playing on the original console. Even if you'd had a choice between playing poorly and not playing at all, the latter is better choice as the games that end up more demanding were often successful for things you will be removing by trying to degrade experience to something even worse than on the original hardware.

Probably the biggest gain you might actually have if you didn't yet would be to switch from Retroawful core to proper PPSSPP, just doing that, even without any special game breaking speedhacks is enough to make at least some less demanding games run well enough to be properly playable. Another thing would be 20 or 30 FPS patches for games that run at higher framerate natively, but that's while providing huge gains, is also just turning the experience down.

In addition to what LunaMoo says, adding a 0.5x mode would actually be a bit complex, and it's a change that would benefit extremely few users and the benefit would be near zero. Again, I doubt that at 480x272, lowering the resolution further will provide meaningful speed benefit on almost any hardware that can run PPSSPP at all. The problem with Ratchet might very well be something else.
