Before I start, I want to preface that I used to play the Japanese version of the game and ran it at 4k with maximum settings without any issues with weaker harder than I'll be listing below.
I am absolutely baffled and shocked by the performance on this Windows Store release - I dip to 2-11 FPS regularly just sitting in the lobby not moving around trying to enter text into the chat box.
Nvidia Geforce 2080
4 tb (2x2) Samsung NVME
Here is a video of what I'm seeing while running at 1920x1080 on the above hardware:
At 0:3 I dip to 18 FPS, again at 0:7 I dip to a mind numbing 2 FPS. As you can see from the above video I am experiencing massive frame drops intermittently while playing in a relatively unfilled lobby. The game will simply drop frames for no apparent reason and does so sporadically while typing, opening menu's, etc. This should NOT be an issue, the game is loaded to an NVME drive that has 3200 mb/s read speed.
Sega, can you please explain what you did with this port?
