Even frame pacing
A frame pacer locked to your display's refresh shows every frame for the same time, so 60 FPS looks and feels like 60.
Kitsu emulator
Your Switch library, smooth on PC.
Dream. Play. Explore.
A free, open-source Nintendo Switch and Switch 2 emulator for PC, built for a smooth, steady 60 FPS.
Windows & Linux · Vulkan · GPL-3.0
Built to play smoothly
Kitsu is tuned for steady frame times first: no hitches when new effects appear, no tearing, no fake frames needed.
Less shader stutter
New shaders build in the background instead of freezing the game, and compiled ones are kept and rebuilt first after a restart.
Made for modern CPUs
The GPU threads get cores of their own and wait on each other far less, so fast desktop processors are put to work.
Sharp, faithful graphics
Vulkan rendering with resolution scaling, FSR and SMAA, plus fixes for foliage, shadows and lighting in the games people play most.
Cheats & mods
Atmosphère-format cheats and game mods appear in each game's Add-Ons, with an on/off switch for every one.
A home for your games
Continue where you left off, see your play time, keep favorites and history, and give every game its own artwork.
