xemu Phantasy Star Online Episode I & II: Extreme slowdowns when menus/hud's are present in game

Title

https://xemu.app/titles/4d53004a/#Phantasy-Star-Online-Episode-I-II

Bug Description

HUD elements in the game are tanking the FPS very hard, PSO natively runs at 30 FPS, when a menu (such as the pause menu) is opened mid-game & there are many NPC's or enemies around the FPS get even worse to the single digits sometimes.

During certain menu screen such as the character creation it can go even lower to 0 FPS (see attached screenshots for additional context)

render scale is set to 1x in all attached screenshots

Expected Behavior

The game keeps running at its native 30 FPS regardless of whats happening on the screen or what menu/HUD element is being shown.

Character Creation Screen (Notice the Blurred text transition, the FPS will stay at 1 FPS until that transition ends)

Character Creation Screen (Once the blurred text loads entirely the FPS goes up to around 15 FPS far from the 30 fps this game runs at)

Multiplayer Mode Via XBOX Live (Insignia)

The game works without problems, network stability is fine, sounds and graphics are fine but its extremelly slow as more characters/monsters and chat bubbles appears on the screen tanking the FPS way below the game native 30FPS.

This also occurs on Kikou Heidan J-Phoenix + but even worse

Updated the initial report and the related #953 ticket running with the latest version of xemu, the problems are still present in both cases.

Updated the ticket #953 with pictures of the game working on XBOX LIVE via Insignia, the game works as intended but sadly the speed is still too slow to play comfortably.

This is also using macos Ventura and the very latest version of Xemu as of October 11th. No improvement with speeds whatsoever yet.

I'm also having issues running this game on the latest version of Xemu (v0.7.71 - Oct 11, 2022). It boots up fine and I'm able to make it online utilizing Insignia, but the frame rates are so terrible it's literally unplayable, despite my modifications in the emulator's settings.

I'm using Windows 10 64-bit (21H2 build 19044.2130), running the emulator as well as the game from an internal SSD, Nvidia GeForce GTX 1650 Ti, Intel Core i5-10300H @ 2.50 GHz, 8 GB RAM.

I wanted to give an update regarding PSO, at least running it on Linux PSO is running at full speed now without any weird graphic issues this is with the following build
