Have anyone else problem with performance when Reshade is enabled ? When I start game everything is fine but after few minutes my fps drops a lot but this problem persists even when I disable Reshade.

Game? ReShade version? Settings used? Do you mean disable ReShade, as in, with the toggle button?

Trackmania Turbo, 2.0.2, some sweetfx effects and bloom + lensdirt, yes

Reduce game's texture quality. ReShade needs some VRAM to work.

How much vram does ReShade needs?

There is no general rule. It highly depends on the game and circumstances. But at least screen width * height * 4 bytes. Depth access doubles that. Than some additional working buffers sometimes (Direct3D 11 on Windows 10 requires a workaround to write the final result of ReShade back to the screen which uses another width * height * 4 buffer for instance). And every texture used by the effects you enable need storage too of course (uncompressed, so it's much larger than the compressed PNG files).

Thanks for the explanations, it help us to understand a little bit more about the plumbers, so which format should we use in our textures in order to save a little extra work to ReShade converting the textures? *.dds uncompressed, *.png uncompressed?

Hey, I'm also having really big impacts on my performance since 2 weeks. I've been using SweetFX for 3 months, and everything was okay. But these days I've been having a trouble: everygame with SweetFX or Reshade runs at 10 fps. I don't know, but it takes A LOT of my FPS. Please tell me what to do, because once you try SweetFX, you can't play with it. For example, yesterday, I ran the ReShade Setup Tool of ReShade with SweetFX 2.0 on Dragon's Dogma Dark Arisen, and even in the main menu, I had like 30 fps. My ingame FPS were like 10-15 fps. I have to say that I'm on Windows 10, but the problem started using Windows 8.1 Pro. I always have my drivers up to date. Some of my PC specs:
GTX 660
Intel Core i5 4440 3.1 GHz
8 GB RAM

I recorded an ingame video. If you need more information or something, I can upload it. Just tell me.

This texture won't be compressed:This texture will be compressed using the DXT3 algorithm:

I jest. Thank you man.

I found out "gauss" effect is bad optimized, consumes some performance.

I could be wrong but my assumption is that some effects are just very demanding and the shaders are fairly well optimized by now though some smaller gains might be possible still.
