So (one) the problem lies somewhere along the lines of multitasking properly?
No doubt is any commercial game magnitudes more difficult than any homebrew, but that problem must exist simply because the input system can't give the desired output - in other words, the games are not being executed correctly enough, and/or the emulated pipeline/GPU can't work properly with the input as well.
I haven't look much into the source, but under what conditions is the GPU being emulated? NVIDIA claims the GPU used in PS3 is some variant of the GeForce 7 series models of graphics chips. I assume that PS3 games are compiled with intended shader code for some variant model architecture of the GeForce 7. Not my area of specialty, but can't you LLE the shading and texturing, and HLE more of the data processing?
Do any devs of RPCS3 know the full extent of GeForce GPUs? There's some documentation (some of which may give a better idea on how to implement HLE, if desired), though not ideal and detailed enough, such as follows:
http://developer.download.nvidia.com/GPU..._Guide.pdf
Also, Nouveau seems to be a step forward with regards to the "mystery" of NVIDIA GPUs. NVIDIA also reported that they would release more info on their GPUs specificially for Nouveau.
EXTRA: I know that, as of now, emulating the firmware isn't the priority, but I mean in the future it certainly could be added along to benefit the full PS3 emulation experience.
