Re: Shaders

I've attached another very simple 'scanline' shader, based on lcd3x. I don't think it's quite as good as the 'zfast_lcd' one I posted earlier, but this shader has the benefit that it scales well on low resolution screens (i.e. 720p). Compared with lcd3x, it has the following differences/advantages: ...

Re: Shaders

Same as before i try modified it Look like this better that before but dot pixel are bigger... By replacing PI with 2.0, you've just changed the 'scanline' spacing. This doesn't fix the problem... Look at how the lines become more uneven as you go towards the right/bottom of the screen: this is bec...

Re: Shaders

Sadly highp shader could not be load... i think my tablet could not handle it.... If the shader failed to compile, I think there should be a log file in your shaders directory - probably called lcd3x_highp.log (or maybe just lcd3x.log). If you post the contents of this, I might be able to see what ...

Unfortunately, It looks like the GPU in your tablet has floating point precision issues ...

Re: Shaders

I appreciate it...my problem with using lcd3x shader just like in my screenshot (snip) Oh... I could be wrong, but that looks like a GPU floating point precision issue... (Android devices can be really bad when it comes to this - it affects many, many shaders in RetroArch, too) Try the attached ver...

Re: Shaders

I made a quick port of the 'zfast_lcd' shader from RetroArch, and thought I'd share... The attached zip file contains two variants: - zfast_lcd: This is a very simple shader (minimal performance impact) that creates an LCD effect by adding a subtle grid lattice to the screen - zfast_lcd+nds_color: T...
