Two things:

a) this is being emulated through prism translation layer (might explain those 1% lows). so if a native aarch64 build were ever released for these games, expect better performance.

b) iirc, there was a Qcomm slide indicating that dgpu support would eventually be coming later. so you may not even have to wait for next gen x3 igpu improvements to see better results.

If QUALCOMM continues on this trajectory and fixes the 1% lows, the Snapdragon X3 Elite' iGPU is going to be fast enough to be considered. Nice single-core speed improvement in X2 Elite.
