Tekken Tag Tournament 2 - Cemu 1.8.0 - 4k

Testing out TTT 2 on Cemu 1.8.0
Solo practice seems to work best but has random crashes, glitches and fps drops. The other modes just crash constantly.
Audio isn't perfect either.
PC:
OS: Windows 10 64bit
GPU: EVGA GTX 980 FTW
CPU: i7-3770K @4.6ghz
RAM: 16GB 2133MHz DDR3
