Until someone invents magic, somebody else's problem field generators, or an spectacular texture scaling algorithm that looks amazing and is super fast.
Ppsspp texture scaling 64 Bit#
I think there the issue is simple: texture scaling takes time. INFO Environ: GETVARIABLE ppsspptexturescalinglevel: 4 libretro INFO BOOT PPSSPP 0b17dd0 Windows 64 bit libretro INFO MEMMAP Memory system initialized. Other important additions this version are support for D3D11, new audio setting in order to deliver better performance with wireless headsets and high DPI display fixes.
Ppsspp texture scaling psp#
Might be worth benching to see if it's better to use a temp buffer in the non-sequential cases.īut for texture scaling perf issues that happen on OpenGL (where we always use a temp buffer currently), this won't help. In previous versions of ppsspp, the game textures was blur as psp games are made for small screen, but in v1.4 you can upscale textures. for better performance and better image quailty comparing to texture scaling. With the exception of swizzled textures (common) and DXT (uncommon), we decode a lot of textures sequentially. A PSP emulator for Android, Windows, Mac, Linux and Blackberry 10. Then we could add a flag (maybe assume mobile/desktop except on Vulkan where we can detect?) to force a temp buffer when scaling, rather than scaling directly? While not using GPU outside of experimental ini-only & vulkan-only setting, a honorable mention goes to Texture Scaling, we limit that a lot avoiding scaling some textures and scaling others with delay, but even with such limits and even using powerful desktop CPU's that feature RUINS frame time, causing stutters and short freezes in many games.
It may be worth testing the performance on integrated memory GPUs, since I doubt it cares much about sequential access, but it may. None of the scaling methods will write memory sequentially, which is not great for discrete GPUs.
