I have encountered an issue with FilmGrain 2 when playing Red Dead Redemption 2 and Horizon Zero Dawn, after like an hour or so of playing the grain will stop floating around and just stays there, still. Weird thing is that i have noticed it only after upgrading my 980 to a 2080, i doubt that has anything to do with the problem though. I really like this shader, been using it for years and this issue really bummed me out lol, please if anyone knows what is going on, help me :lol:

It's probably an issue with random noise generator algorithm, where seed (perhaps number of frames or time) gets to high-enough number, everything breaks.
I have made some film grain shaders that wont experience this problem, like SimpleGrain.fx .

I haven't tried Reshade 4.8.2 yet, so i don't know if that fixes what it's causing the issue, but wiith 4.7 i fixed it(after some research lol) by changing this line

float noise = sin(dot(tc, float2(12.9898, 78.233))) * 43758.5453;

with

float noise = sin(dot(tc,float2(12.9898, 78.233))) + sin(timer*0.0025216);
        noise = noise * 43578.5453 * 0.5;
