I tried it out, it surely does give me some boost in fps, but the responsiveness is amazing, although I have some visual glitches as well, so I understand everyone else's concerns. I haven't messed around with any of the settings, everything is default. For demonstrating the visual glitches I have with it, let me show you a couple pictures.

I don't know where this box belongs to, but these boxes usually appear when an item that is supposed to be there isn't installed at that moment.

For example like this, when I remove the intercooler from the engine instead of rendering whatever under it correctly, it shows a huge white box, that was the case with supercharger mod back in the day as well, this only happens with mod parts in my experience, so maybe donnercharger mod support should be considered.
There are some other little issues like slight flickering on shadows cast on some certain items and etc. (and can provide screenshots of them if need be), but I'll take the fps boost and responsiveness anyday. I am really glad that you reintroduced this feature to MOP. Thanks
