That is some good data. Was the Bloom Effect, Chromatic Abberation, and Distortion to Microbe Backgrounds making much of a difference? Or were they each less than the effect that Anisotropic filtering had?
For testing Linux, it would be fairly simple to make a bootable USB, like Ubuntu for example, and just try it out without installing it, see if you like it much. Might be interesting to see if Thrive runs any better on Linux?
If the GPU memory was limiting performance, maybe reducing the quality of the assets would help with that. Seems like it would be worth looking into, seeing if Godot supports that easily.
Do you think you will continue playing Thrive with all of the performance affecting options turned off, or are there some that you think are worth it to you to enable? (Aka, what settings will you be using now that you know the performance effects?)
I have gotten used to playing Thrive with low FPS, so I will probably play sometimes with the performance affecting options off to marvel at getting some extra frames. lol. Also, since I play with OpenGL mode (it seems smoother), it seems weird not to be playing with the blinding effects of Bloom.
