God of War Chains of Olympus cinematics flickering with non-buffered rendering

[LunaMoo]

Setting rendering resolution above x1 changes blurry effects like bloom and similar making them sharp and awful because they're sampled from the render, so if that's just the usual bloom issue, you have 3 choices:
- use "Lower resolution for effects(reduces artifacts)", balanced is usually best choice since safe skips some layers at times and aggressive might reduce resolution of more things pretty easily,
- change your rendering resolution to x1 ~ sometimes the only option if the hack fails to detect it,
- mod the game itself.

It could also be something else, ie Vulkan is still pretty glitchy so in case you're using VK backend because last release was pretty much dedicated for it, I would recommend trying different one like D3d11 or OGL(which quality/compatibility wise is still the best, althrough also more demanding).
