Textures loading problem

[[Unknown]]

The textures won't load and will show as black instead if you don't have enough VRAM.

Keep in mind that a 4K texture pack means textures are 8x the size on each side. Additionally, replaced textures are always 32-bit color. That means a single original pixel which would've required 2 bytes now requires 256 bytes.

So if normally emulating a game might require say ~100 MB of VRAM, it would now require 12 GB of VRAM with a 4K texture pack.

When we try to load a texture and you're out of VRAM, graphics drivers don't always handle this well. PPSSPP may crash, but in most cases it'll just result in a black texture. That's what causes the black.

Your operating system will most likely first try to swap RAM or even VRAM to disk, which will tank performance fast. You do not want to run out of VRAM. If you want to use 4K texture packs, you'd better have a video card with tons of VRAM like the NVIDIA GTX 2080 Ti.

You can use a tool like GPU-Z to monitor your GPU's load and VRAM usage to get a sense for whether this is a problem you're experiencing.

JPCSP hasn't run all the games I like well, but if it works well for you - great. I'm glad you've found a solution.

But just to maybe state the obvious - I don't know much about JPCSP's texture replacement feature, but I'm pretty sure it doesn't use the same hashes as PPSSPP does if it has such a feature. PPSSPP's hashes are based on a seed value that is just a number we made up. If you're trying to just use a JPCSP texture pack with PPSSPP, it obviously won't work.
