GTX 1650 TI
What's wrong with it? Is it GPU related problems?
No, not exactly just yet. I'm trying to figure out why there's so many FPS drop comments from posters. Unlike y'all, I haven't had any, though I am running a 5700 XT. Though a 1650TI/1660S aren't exactly high powered cards, they should be decent enough to handle most modern AAA games at 1080HD. Can't say the same for a GTX 780, which is like, a 10 year old card now and may be something that would cause problems.
As for the "All the other RPGM games work fine for me" argument, this is a different scenario. The devs added a few plugins (such as the rain effects) which could be causing problems or be taxing on GPUs, so I'm wondering if the issue is that people are expecting old GPUs (or in many Android/Joiplay users' cases, their phones' APUs) to play games like this, or if the dev didn't stress test their games with the plugins installed.
Regardless, I'm also just a translator. I'll add little things and features to the game to ease players' progress or improve their game experience, but aside from some minor bugfixes, I'm not going to troubleshoot something this big that I'm not responsible for.
