PCGamer reports that Fallout 76 now has a hard 63 FPS framerate cap. Before the update on November 5th, the game would run at the monitor's refresh rate. Bethesda hasn't made any official note of it yet, but the cap will presumably mitigate the framerate-related speedhacks that plagued earlier Fallout 76 betas. The FOV is still hard-locked too, but fortunately it seems to scale dynamically with the monitor's aspect ratio, which should make playing on ultra-wide monitors more palatable. As for the framerate cap, it appears to be fully enforced and hard-coded into the engine. Previously, Fallout 76 would run at your display's desktop refresh rate, up to 75Hz, or half the refresh rate on high-end gaming displays (eg, 72fps on a 144Hz display). Now, the maximum in-game framerate is 63fps as far as I can tell, slightly higher than 60 in order to reduce microstuttering. That applies to 75Hz and 144Hz displays as well, though if you run at a lower rate like 98Hz you'll end up at 48fps if you set iPresentInterval=1. There's only one more beta period before the game is set to officially launch next week. Bethesda may revisit the framerate lock and eventually allow higher framerates in the future, along with FOV adjustments, but that remains to be seen. There are likely plenty of other higher priority items to fix right now.
