I'm wondering if the changes in GPU utilization in Mavericks is causing After Effects CS6 to have less than normal discrete VRAM on application launch. Before updating, the preferences menu in AE would tell me I have (on average) about 800-900 Mb of current memory available. Now, I am getting substantially less, as low as 300 Mb on average. I have noticed the app performance when using a plugin that utilizes openGL for acceleration has gone way down as well. I realize that the plugin may need to be updated for Mavericks optimization, but that doesn't change the fact that I'm seeing less available VRAM in AE on startup. some helpful details: running on 2012 rMBP with 16gb ram, nvidia geforce 650m (1Gb VRAM) with up to date CUDA driver. AE has also been updated to the proper version meant to run on Mavericks. another thing I noticed is that in system profiler, it now lists available VRAM for the integrated Intel 4000 card at 1000Mb, where before I think it was somewhere around 756Mb? Has Mavericks allocated some of my dGPU memory for use by the integrated card?
