It means that if your screen have not the same ratio as the image of the game, this option will stretch this image to adapt it to your screen... So the game will be deformed...

♦ 12HR Time Format >> Maybe for the hour of your saves...
♦ Draw Wireframe >> It draws lines on the graphics, I don't know what is it used for !
♦ Encrypt Save >> For prevent some corrupted saves I believe

My original idea was to just put non-trivial/performance/graphics options since the rest of the options seems auto-explicative to me. But it doesn't seem so to everyone, so I will add the rest later (I have a test tomorrow and other things to do so I don't have the time to do this now).

I will change some things too to reflect the new UI (I think I will add the options only from SDL UI for now until we get a working Qt UI). Maybe even some screenshots.

Thanks for your work, it will be more clear for everyone !

Henrik in the latest builds (on android 4.0.3) many crashes in much of the games, no load nothing only start game and 2 secs on gamelist and crash ppsspp

any idea?

testing another next build and crash only in other games etc is strange

ups incorrect thread sorry

[solarmystic]

I've a question about this option and it's explanation:-

Quote:Hardware Transform: uses vertex shaders to do T&L on the GPU instead of doing it in software on the CPU. It should be identically visually to SW transform but it isn't, there are some small differences between the implementations. It's faster depending of the GPU.

Why does disabling this function result in a speed up for certain games which are CPU heavy when logically speaking the opposite should occur?

For example, in a CPU heavy game like Tekken 6 (completely saturates one CPU core and does not attain 60 VPS), one should expect that disabling HT would result in a performance loss, but I instead gain a significant amout of performance when HT is disabled. The GPU is not the limiter as increasing/reducing rendering res or 2xSSAA doesn't affect the VPS which means that it is CPU capped.

What about anisotropic filtering?
How many times is the best settings?

16x, always. Negligable speed hit on most modern PC GPUs.

And as solarmystic said, you have to choose the highest setting for the best results

wht about true color????

I think it's like the option on the PSP-3000 named "Color Space" which enhance the colors compared to the previous versions of PSPs which have lower quality screens

[kevke96]

I dont know if PSP games use True Color depth, but from my experience it should always be enabled (if you dont have a gpu from the last century, at least. They dont like it).

Can someone update the opening post with the new options, please?
Edit: Too slow... Yeah it should give you better colors.

I don't think this is related to games because when you enable this option on a PSP-3000, the changes are immediately visible, it works even on the menu, so, be in-game or not doesn't matter

But what about android?
I'm using a Motorola razr xt910.

You just have to test it
If the 16x setting makes your VPS decreasing, choose a lower setting like 8x, 4x or 2x

wht abut xBRZ???

[kevke96]

xBRZ is a texture filter similar to HQx. Just tick 3x scaling, fire up a 2D game and youll see.
Edit: Just tested it with a few 3D games. It really scales up every texture you throw at it. Can look nice or awful depending on the game.
