Are clouds handled by the gpu or the cpu in fsx?

?

He wants to know if the clouds are processed by the video card processor OR the MB processor. Good question. Just exactly what textures DOES the GPU process? If anyone knows. and what calculations does the CPU perform within FSX? Might as well get really really really really technical.Oh what the heck, might as well ask which calculations are performed by which core of the dual processor. What function does the dual core processor play in FsX or Fs9 for that matter? What work is actually being done by what?

Speaking rather generally....CPUCalculation such as fly dynamicsFS9, FSX+patch : second thread fetch of scenery textures.GPURendering of texturesAA - anti-alias (if you set this on the card) of screen. The amountof work here depends on screen size, AA level and image varianceAF - handling of MIP defined textures. Amount of work here dependson level of AF and the MIP level supported by software.So, are clouds done on the GPU - well, hum sort of. So cloudsare textures and get rendered by the GPU, but sorting out wherethey are in space, how they move, and the fetch from disk is doneby the CPU. 2D clouds are easy to render - have little impact onGPU. Finally, clouds have a lot of variance as they are not completelyopaque - so clouds are a real killer for AA calculations.Tom
