Encounter an error while trying to play game on rpcs3.

So what? Making emulators is really difficult. The success of one project doesn't mean anything for another. Let's make it perfectly clear with a big nice font for everyone to see:

rpcs3 does not run a single real game properly.

So yes, if you want to play GoW this decade get a PS3, that simple. I have a PS3 with CFW and it's quite nice.

I didn't meant it that way, what I meant was that it been so many years, but still we can't play any 3d game on rpcs3, even after development of directx 12.
It would be very good if I can play GOW 3 with at least 30 fps on my windows 10 having directx 12.

Even Xenia (Xbox 360 emulator), has played a game called A-Train HX 3d game at 60 fps with the help of directx 12.
