Look at this Video of Tomb Raider Legend (old game ) run at 4K resolution (with FXAA and 16x anisotropic filtering), and compare it to any normal 1080p output video of the game on youtube.

But the current emulation cores dont stop there, they upsample textures, apply anisotropic filtering, and when this is then filtered on the 2D output image level, it looks much better, because the initial result a binaural filter (f.e.) gets applied to has much more detail and resolution to begin with.Īlso higher internal resolution is the best form of anti aliasing available, also the most costly (performance wise ) - which is why DSR (nvidia "brand" term for upresing older PC games using their drivers, really is much more than just hype. What does higher internal resolution do - for starters, it creates nicer edge definition on polygon models, so every round surface looks better. (And needs HW acceleration (dynarec), on the Switch, and pretty much everywhere else.) Getting a game to run at a higher render resolution is much more costly performance wise.

Thats the same every TV does - internally at no cost. We want our games to be calculated at a higher internal resolution, which is where all the good stuff is at - we dont care so much about "display (buffer) output" resolution, because thats just the 2D output images (frames) uprezed ("scaled"). Thats what we are looking at here as well. Remember, when Sony and MS were all like "we have ourselves 4K resolution consoles this generation", and then maybe 2 games ran at those resolutions, but - everything did _output_ 4k resolution? Theres basically only m4xw working on it.īoth are increasing resolution, but the difference between internal resolution and display (buffer) resolution is whats at stake here, and the difference is huge. When will better be available? How does longway out to never sound? Implementation isn't straight forward (as you see with PPSSPP core advancements on the beta status), there are other cores to unlock first. Stretching an image isnt upscaling it either, thats just stretching it and is only concerning output resolution as well. 1st one would take hardware accelleration (GPU) on the Switch, which for PSX games (PCSX Rearmed), we dont have.īest bet is to apply a shader to the 2D image, and hope it looks better. With one a games 3D content (polygons) is calculated at a higher resolution, with the other one, only the output image (think of it as a 2D image) is upresed.Ģnd one takes almost no computing power and can be done in ones sleep. OP is tatlking about render resolution (internal resolution a game is rendered in in the emulator), not just display buffer resolution (resolution of the output image).
