In my experience CU mainly improves the min fps and therefore makes the Framerate more stable. I don’t think the selling point ever was to drastically increase the average fps.

Very comfortable, i was expecting worse given its size. It is not as comfortable as a controller but the most comfortable Handheld i have used.

Epic and GOG work really well with the heroic launcher, the Gamepass only works via streaming (since its Microsoft) and i believe the EA App can be installed via proton (starting the installer exe through proton like you start a windows game)
