LÖVE

Even though I don't have enough time to be as active on the forums as I used to be, this doesn't mean I stopped using LÖVE! My latest creation is a (rather simple, really) tool to test Variable Refresh Rate (meaning Freesync, G-Sync, Adaptive Sync) on pretty much any OS on which LÖVE runs. Although a keyboard is required for proper usage.
The repo for the tool can be found here, as well as a screenshot. Instructions are available when running the program itself.
