Anyway, I have to say cube is not representative of every game. For example, in Kingdom Hearts at the first playable scene in a new game, 32-bit gives me 503 vps, and 64-bit gives me 499 vps. I've seen 64-bit better for other games, so it just depends. I've never seen such a large difference in a real game, though.

Synthetic benchmarks are, as always, lies.

You are of course, correct.

I redid the test for actual games, and the results are mostly within the expected deviation.

Games which offer significant performance increases in 64bit version are often those that aren't CPU limited/constricted to begin with at 2x RR with unlimited VPS.

Also, performance differences between the 2 builds are often negated when the emulator is run at a higher Rendering Resolution (4x RR or 1080p fullscreen), so that the situation becomes effectively GPU limited instead of CPU limited.

My point was that the 64bit build innately offers lower CPU overhead for that particular test, and it seems to be true when other games are tested at that same 2x RR which means that the GPU could be utilized fully at those given settings instead of being bottlenecked by the CPU.

You are obviously not going to notice it with your monster i7 rigs which have tonnes of the CPU power to spare.

PPSSPP Modern Testbed:-
Intel Core i5 4690K @ 4.0 GHz
NVIDIA Geforce GTX 760 2GB GDDR5 VRAM @ 1138/6500 Mhz
16 GB DDR3 RAM @ 1600 MHz
Windows 7 x64 SP1

PPSSPP Ancient Testing Rig:-
Intel Core 2 Duo T9550 @ 2.8GHz
ATI Mobility Radeon 4670 1GB GDDR3 VRAM @ 843/882 MHz
8 GB DDR3 RAM @ 1066 MHz
Windows 7 x64 SP1
