It might avoid some of the crashes. I stopped running because on newer hardware (for some reason) certain levels capped at 30fps, even though I had it set to 60. It would be 60 everywhere else. Also the crashes were also the reason.
Maybe I can experiment with this idea, though it would clash with the previous runs, it may be the reason for a lot of issues.
No you don't have too infact I actually recommend using the iso: https://www.speedrun.com/lego_island_2_pc/thread/0aj35/1#uioiv
I just wanted to make a post for those wondering about ISOs and what not. Besides livesplit and OBS, I use an iso of the game now instead of my disc as it runs so much cleaner, and faster and (so far) much less crashing. And optionally if you want to, I also use a program called cursor lock that locks my cursor to the game window. If you think that might get annoying, just press the windows key to get out of it and do what you need to do, once you're back in LI2 it'll lock it back up. Also it only locks in LI2. if I start using something new, or need to make changes, I'll come back to this.
Recommend Iso: https://www.myabandonware.com/game/lego-island-2-the-brickster-s-revenge-bd2#download
Recommend Daemon lite(Use this to run iso through. You can just use the free version): https://www.daemon-tools.cc/products/dtLite

PHT = Peppers House Teleport
Several times in the run you teleport to Pepper's house to gain time advantages, but a lot of the time it has a chance at crashing your game, here's how to fix that.
First things first in your mod loader, make sure you're set resolution is a step below what your screen resolution is. For example: My screen is 1600 x 900 so I brought it down to 1366 x 768.
Next make sure in your games properties, under the compatibility you have "Disable fullscreen optimizations" on. (I'm not sure if it does much, but I have it on anyways.) You don't have to have admin mode on but don't have compatibility mode on as it adds a second or two to loading screens. also be sure under "Change high DPI settings" that you have "High DPI scaling override" on and set to "System".
This actually helped me stop crashing on PHT's and maybe crashes in general. Hope it helps y'all.
What are your mod loader settings at? Because I am in windowed mode but it's not working as well as yours was.
