Basically, they made some changes to the Xbox One CPU so that it can accept and execute PowerPC instructions of Xbox 360(in a x86 environment) by emulating some functionalities of PowerPC firmware in the chip. They have been working on this since 2007, at that time they didnt have Xbox One, they were testing it on x86 hardware. Xbox 360 emulation in Xbox One is a combination of both hardware and software emulation. Well, Emulator is a hardware device or a program which emulates the functionalities of a target device and allows real time debugging of embedded firmware(of target device) in another environment(for which the emulator is designed). As per you an emulator is only software that plays console games on PC. I'm surprised you have more FPS in the air, maybe the snow effect affect it? What I noticed on my end is that the game doesn't feel as smooth in the air, even when rivatuner still reports a steady 60fps, the game feels somewhat slower in the air, it seems to be a combination of character animation speed and camera movement speed that make it feel like 30fps in the air while suddenly being smooth again when landing on the ground.Ĭlick to expand.It seems like you have no idea what an emulator is. Hopefully in the future with more optimization it won't be as gpu heavy, because otherwise it might be a big issue for when we want to start rendering games at higher resolutions, if I enable 2X resolution scale, up to 1440p on SSX, my framerate drops in the 20s. The emulation process in the DirectX12 branch of Xenia is really GPU bound, it does give me way better performances than anything I tried on RPCS3 though so I'm not complaining, that's probably because my CPU is actually old now (I7 2600k) so I get better performances with Xenia. Yes from everything I tested on Xenia it relies heavily on GPU, my GPU load is higher than CPU load by a large margin, with my GTX 1080 being in the 90%+ usage most of the time, with the game actually being rendered at 720p.
