I can’t make it run at game framerate. I’m testing with default values for PSX games, I tried to lower manually the scale to 1x and 2x and it runs fine but obviously it doesn’t look good. I’m wondering if the shader is usable since my machine is rather new, i5-4670K and 750 Ti.
It is indeed very slow, as the blurring parts are all done in a single pass, which is always demanding. However, it’s no different from any of the other halation stuff in how it works, so you could try just substituting the regular lottes shader into any of the more performant, multipass options.
I was shocked since I thought all the included shaders were at least in usable state. So you mean to use the original lottes shader and add the halation as multipass?
I really wanted to use this shader since it fills a gap for this kind of late 90’s CRT TV’s. Perfect for PSX and Saturn.
I run some tests and found that version without halation is very competent, actually I don’t see any difference on halation effect, but I lose a bit of texture/dithering filtering.

It’s usable, you just need a strong GPU. What kind of speed do you get with your 750 Ti? I get full speed on my work machine (radeon 270…? I forget).
In most scenes, the bloom is really subtle and just amounts to a slight brightness bump, but you can see it more in a white-on-black situation: lottes lottes-halation
you mean FPS? I tried to enable “Show FPS” but nothing is shown on-screen. On windowed mode I see the framerate on title bar but then the game runs at full speed 50FPS.
My card is an overclocked 750 Ti SC so it shouldn’t be too far from the 270, about 15% less power. Anyway, I don’t want to fry it, much less for subtle differences.
edit: the more simple lottes has also difficulties in some games : ( how sad, this shader is superb.
I just tested crt-lottes-halation with defaults on my 2500k GTX 570 machine with Einhander and didn’t have any issues getting full speed. No sound crackles with hard sync frames 1 either.
My CPU is an 4670K, but my GPU is worse, a 570 is about the Radeon 270.
I included RetroArch to nvidia panel and set it to max performance ( I had a previous beta included though), and “it looks” basic lottes works fine now. halation is still no way. I overclocked (over the SC model) +350 in memory clock and +150 in core clock without success. One thing to note, bringing MSI afterburner to focus and in front of emulator made the game run full speed or near, back to game, slow play and sound.
Yeah i get poor performance with crt-lottes-halation shader as well, i have a GTX 970 4GB and i7 cpu @ 4.2ghz so i think i should be able to run it no problems
Interesting… I have an i3 @ 3.6ghz and a Radeon 7750 and have zero issues with Lotte’s Halation…(been my favorite shader for a while)…
Looks like an issue on modern nvidia cards.
