A new update to Proton has brought a few fixes for particular games, with Street Fighter 6 getting a key update before the game’s launch next month.

While just a bullet point in the patch notes, Valve’s engineers have fixed a memory leak issue that would plague the game during video playback. Memory leaks can be quite severe in gaming, as it asks too much of the RAM. Eventually, this leads to a crash as there are no more available resources for the game to continue working from.

This would cause Street Fighter 6 to potentially perform less than the required 60FPS for competitive play.

The update is expected to be rolled into the next iteration of Proton, 8.0-3, along with a bunch of other updates for various games.
