user9154: I am just playing arround with the new trapcode suite in after effects working ina linearized color space for a better control over color and effects.
Somehow I get really bad rendering on parts of my footage where its supposed to be more smooth.

On the screenshot I am using trapcode mir for the fllo, tao for the spiral thing and shine for the light rays. If you take a closer look at the sprial geometry you can already see the jagged gradient where its supposed to be smoother. I am also working in 32Bit soo I don't get it.

user12369: I use the trapcode suite as well, the issue has more to do with the fact that even though you may be working in an sRGB workspace at 32 Bit; your monitor output is 8 bit. 10 Bit monitors are available but unless you forked up a lot of cash - you are viewing 8-bit. 
The way to solve gradient problems like this - with this as well as any other gradient in AE/Premiere/PS; is to add an adjustment layer to the top of your project; on top of all layers. Add the standard NOISE filter. Check monochromatic (or un check use color noise) - you don't want color. Gaussian sometimes looks better; it's one of two options on the NOISE pop-up. 
Typically; I use a setting of 2 - 4%. But it really depends on your comp settings. If I'm working with RED 5k footage I typically have to do 1-2%. 
Lastly; honestly I almost always add NOISE to all the work I do; even if it's just 1% on a nested timeline for output. It solves a lot of aliasing problems and is a standard trick in post many people use. 
Hope that helps.  

user12594: If the above render is a RAM preview, the default preview quality may be the culprit: Preferences > PREVIEWS > Color Management Quality > More Accurate.
