PCSX2 makes me feel like this when I got full screen 1920x1080 in glorious 4:3 with a triangular scanline filter.

I've been replaying all the old ps2 NFS games upscaled to 4k with a lottes CRT filter. I've been dumping my textures too, once I've got them all I plan to run an ESRGAN AI upscale across the board to render them at 4k native.

I've been doing this with all my PS2 games, I will be doing it with some PS1 games too.

I love PCSX2. My biggest problem with it is how many games have broken visuals with hardware rendering in higher resolutions, though that's mostly down to the freaky alien math the PS2 used.

I played Genji: Dawn of the Samurai earlier this year and it's a pretty good (bad?) example of the types of issues you typically run into, which lots of broken DOF and bloom effects and ghosting and double images everywhere

It legitimately strains your eyes after a while

Can't wait until that new Parallel-GS renderer makes it way to PCSX2 as it's supposed to fix these kinds of problems
