FreeSync vs. G-Sync Compatible: Unexpected Input Lag Results

Stefan Mileschin · 28th January 2019, 10:23

YouTuber Battle(non)sense decided to test whether there were any differences between running an ASUS VG258Q monitor in FreeSync mode vs. G-Sync mode on NVIDIA and AMD cards. They appear to perform quite comparably, although certain combinations (e.g., AMD GPU + FreeSync) appear to offer lower delay. One interesting find was input lag of 10ms or more with NVIDIA when adaptive sync was turned off entirely. You can now use an adaptive-sync aka. FreeSync monitor on an Nvidia graphics card without any workarounds or hacks as the Nvidia driver now comes with native adaptive-sync support. So I set out to test if there is any difference between running a monitor in FreeSync, or G-Sync Compatible mode. What did look like a fast and straight forward test turned out to be quite a challenge which lead to some interesting results and raised more questions about adaptive sync monitors on Nvidia graphics cards.
