As we reported on our pages, starting with the release of firmware update 8.0.1, Nintendo Switch introduced the possibility for developers to overclock the CPU and GPU of the hybrid console.
After seeing the first significant improvements with the loading times of The Legend of Zelda: Breath of the Wild and Super Mario Odyssey through overclocking of the console CPU, Digital Foundry took under consideration the Switch version of Mortal Kombat 11 finding that even the fighting game of NetherRealm Studios makes use of this sort of Boost Mode.
As explained in depth by Richard Leadbettere of Digital Foundry in the video that you find at the top of the news, Mortal Kombat 11 benefits from GPU overclocking when playing in portable mode, thus stabilizing game performance and mitigating the impact of dynamic resolution that fluctuates between 480p and 384p. This is the first third-party game on which such improvements have been noted.
The Nintendo Switch graphics card has always been limited to a computational speed of 384MHz, while the processor stopped at 1020MHz: now they can reach up to 460MHz and 1785MHz respectively. These overclocks, of which Nintendo has never curiously spoken explicitly, bring the console closer to the performance of the NVIDIA Shield Android TV equipped with the same Tegra X1 chip on which the hybrid platform is based.
