Helium Windows trys to provide a modpack of the best optimization mods available, make for maximum performance. Thanks to Rezombium/me, it often is better than other optimization modpacks in benchmarks, and when it doesn't, I see why to make it better. Helium is with maintainability and quality in mind. We also added mods for quality while still aims for perfect frames as a 32, 32, 32 renders it runs solid 600+. Also with 15, 15, 15 renders it can run 900+. (If that causes issues, feel free to ask for support in our Discord server and we'll try to help out! Also join if you have any feedback you want to share - all is welcome.)
