Hi,

im maya guy messing around in xsi from time to time with some basic stuff.

Short description of problem:
I have 10 still targa clips, each is ran thru fxtree for basic colorcorection, my lowpoly model has those applied. Playback is super slow in textured/tex decal mode, but normal in shaded/wireframe/all other. When i delete the fxtree stuff, it plays normally in textured again.

Long description of problem:
Ok, so i sourced about 10 still targas (1-2k textures) and ran a clip of each thru FXtree for some really basic colorcorrection (2nodes max for each clip), basically because i noticed that viewport in textured/tex decal mode perfectly shows all the changes made in fxtree unlike when i colorcorrect in render tree. The scene is just a low poly model with these 10 simple shaders using those clips as diffuse/amb but if i start viewport playback even without any sort of animation/sim the timeline plays incredibly slow and cpu usage is at max. when i play in wireframe or any other mode that doesnt show textures, its fast and cpu barely does anything. When i delete the clips from fxtree one by one it gets faster and faster again. Also when i navigate in viewport without playing back, its smooth. it only slows down when i start the playback.

Are the clip results from fxtree not getting cached and get recomputed every frame even for viewport display?
Is there a way to turn on cache or disable fxtree recomputing for viewport on clips that are just still frames? or something..
Or is this just how fxtree rolls and i cant do anything about it?

I tried messing with options, livecaching for fxtree nodes, putting all of them into both one tree and separate trees, image cache size in preferences, lowering viewport ogl texture resolution to 64, still slow in the same way.
My specs are q6600 at 3.5ghz, 4gig, hd4870 512mb, 7200rpms, xp32 but this cant be hardware problem, ive run crazy scenes in maya smoother than this xsi sphere with one fxtree color corrected texture on it…

Any tips or info is welcome
