The title Hyper Light Drifter was meet with critical success after it’s launch on the PC early this year and the title keeps getting updates. One update many wanted was a 60FPS option, and finally, that is being added into the game.

Many moons ago, shortly after launch, we stated that a 60 fps conversion of the game was no small task; it would take a large pile of months and much effort to implement, if it was even achievable at all. Now we can proudly present our latest update and say it has absolutely been worth the work.
This conversion was indeed a massive task to undertake: we worked through over 115 thousand lines of code the past several months in order to make this happen, manually changing timings of each object and enemy, fixing the dozens upon dozens of little problems that arose when changing frame timing, optimizing the game and testing the bits out of it internally.

Heart Machine spent time re-working the game to add in 60FPS and the option has really helped more people enjoy the game on PC. Other features got added to the game too.

Boss Rush + Newcomer
As no small aside, in addition to the frame rate boost, we have a Boss Rush mode with new achievements! It can be unlocked after you beat the game in the standard mode.
We also have a “Newcomer” mode for folks looking for a less intense challenge. It will have a limited set of achievements in it, so players will have to beat the game on the standard mode in order to get everything.
