There’s a new version of ReShade out now, and it has a new feature designed to cut loading times significantly. ReShade 4.9.0 adds a new effects cache, which means effects you’ve compiled for games will be stored on your PC rather than recompiled every time you load your games.
We’ve highlighted a bunch of ReShade-based graphics mods here – some of the best Witcher 3 mods use ReShade, and the tool has been used to add ray-tracing style effects to games like Resident Evil 3 and Doom (2016). It’s a powerful tool, and you don’t need to limit yourself to predefined presets – ReShade gives you a lot of extremely granular control over a whole extra layer of post-processing in countless games.
The trouble is, once you’ve added a bunch of effects, load times can get pretty long – previous versions of ReShade needed to recompile each set of effects each time you loaded a game – or even when you alt-tabbed away and then back in. Fortunately, version 4.9.0 saves your effects, and after the first time you compile them, you won’t see longer load times – they’ll be ready to go.
