I was planning to try out speedrunning the game on PC (Windows 10) but i'm having such performance issues (having lags for hit effects and on audio effects playing), has anyone in the community face that issue and if yes is there a way to fix it?

add me on Steam or Discord.

Hello, sorry for the very late response but i don't have both steam (i have an account but i don't use it on my pc currently) and discord (i don't have an account) i can give you a brief explanation on what i have a problem with , during gameplay or in general when the game try to load some assets (such as the main menu when exiting the map, or during the gameplay when an opponent gets knocked out to show the KO image) it seems that it have a little stutter with the audio stuttering too.

I'm using the ISO PC version on the game (from myabandonware) on a windows 10 pc. I also tried implementing dgvoodoo2 in hopes of fixing the issue and while it was slightly better , it didn't fix it completely

If you want me to add some details i'll give you here.

Game is a buggy mess on windows 10 and newer, unfortunately. No known fixes

Update:

Not a perfect fix, but it's better than nothing. As it turns out, game's background music is the culprit for lags, so you just have to delete it. It's strbgm.vas file.

That's truly works.

I uploaded fix using DxWnd. Finally PC version is working again. You can put your background music back up. https://www.speedrun.com/tmnt2bn/resources/69u78

Thank you very much it may seem late but still i really appreciate it
