As of the moment, I'd say this is a fairly alright custom build! Playing in 60fps plus feels nice, and I really appreciate the extra gif features and functions.
However... I can't really see myself using it personally for a few key issues.
First, Software barely gets a boost in FPS despite the counter claiming otherwise. I'm assuming this is some kind of limitation of the engine as even Kart's interpolated builds and Doom don't go over 35 easily in Software. OpenGL works a hundred times better for interpolation and I assume most use it for the models and such anyways.
Second, it fluctuates in FPS really, really badly, moreso in OpenGL. Considering I have a fairly powerful gaming laptop that can run modern games at max, this shouldn't be happening. Kart's Moe Mansion build doesn't have this issue, to compare. It's really disorienting to deal with.
Third, It feels like there's input lag? In Kart it's less of a prevalent issue and I can play with fair input delay online, but here in a precision platformer that becomes far more noticable and can really mess up timing.
Lastly, the installation requires you to overwrite the .dlls the base game comes with to run and if you at any point want to use the default srb2win.exe, **YOU MUST** have the original .dlls backed up or the game will refuse to launch.
