Thanks for the info.

I have no interest in supporting Thallium as the mod has been nothing but trouble, from misleading users about the true frame rate by re-presenting old frames, taking crazy and random stabs at trying to inflate the FPS counter by running its calculations on another thread, to directly taking code from this very mod under terms that violate Sodium's licensing, and deleting any and all criticism of their practices or claims.

There might be one or two micro-optimizations in Thallium, but you are certainly not missing out on anything. I have yet to see any evidence the mod is anything more than an attempt to reap ad/linkback revenue from users who do know better.
