Major slowdown in Paper Mario: TTYD: Riverside Station Basement

[BgoodGaming]

Okay so I'm running Paper Mario: TTYD on my GPD Win 3 and so far up until this point, the only slowdown that has occurred was during some (not all) paper effects and when using Flurrie to blow away fake decoy objects, however once I reach the Riverside Station in Chapter 6, whenever I use the elevator to the basement, the game suffers major slowdown (10-15 FPS) when using the elevator and when I'm in the basement where I need to pull the lever to activate the bridge and clear away the smorgs that block the lever. I have no idea why Dolphin struggles to emulate TTYD! It really makes me sick because no other GCN game has this issue. I did have some slowdown when fighting some moblins in the Foresaken Fortress in Wind Waker, but I think I had the wrong settings enabled or disabled in Dolphin. Someone who's a dev at Dolphin please consider fixing this issue. It has something to do with the "bounding box", which needs to enabled to prevent graphical glitches, however the slowdown in the basement seems to go away, with the cost of major graphical glitches. I'd still appreciate it, if you guys took the time to fix this issue, it's really annoying and I doubt Nintendo will re-release TTYD anytime soon on the Switch, unlike Super Mario Sunshine.

You could try changing the backends. Direct x is usually better for intel igpu that that device probably uses. It also possible it running into a cpu limit. You could try using the high performance power plan in window and intel command center. If the slow down in wind waker is short then using hybrid ubershaders and compile before start should help. Graphic setting would be useful though.

It's probably bounding box effects in that area on a weak processor/igpu.

Tried using OpenGL and that didn't fix it. I'm about to go into Chapter 7 and I don't feel like going back to Riverside Station via the train. Like I said, whenever some paper effects occur (such as Flurrie blowing away objects) the game slows down and I have no idea how you fix this? It's not my ISO, as far as I know and I'm on the latest version of Dophin. Also my Intel drivers are up to date.

I wish I could overclock my GPD Win 3 but I'm not risking it since to gets very hot at times and it would defiantly destroy my device if I tried to overclock it to 3 GHz. I think the GPD Win 3 runs at 2.5 GHz. It looks like the Intel processor is outdated since it struggles with bounding box effects. I hope this isn't still an issue when the Steam Deck is released. I can't find anyone else with this issue that is running Dolphin on the GPD Win 3. Am I the only one?

To clarify this problem: The game uses a feature called "Bounding Box", it is needed for some cases (ex: going through a pipe, turning into a rollling paper, etc.) those effects (ex: Flurrie blowing away things, Ships turning into the other side, etc.) are the effects of the bounding box, which they are demanding on an iGPU/Slow Processor, there is nothing you can fix this, unless you upgrade your pc or buy another which has better hardware.

I like how the Intel drivers for the GPD Win 3 keep getting updated yet this issue still remains unfixed.

Somebody please think about fixing this issue with the Intel Core i7-1165G7 processor. This one isn't outdated, as far as I know and it might be possible to optimize Dolphin to where the game no longer slows down during these transitions.
