Correct, just finishing testing. BF1, BF5, and 6: pressing A or S makes the game stutter or drop frames. W and D are not impacted by this bug.
This must be the javelin software bc it all started after the update.
have you tried a keyboard that doesn't have the A and S bound to Fn key to switch between F keys and multimedia? I returned a keyboard that had that because it caused conflict with SOCD. but maybe that is your issue too? It silly to have a marketed "gamer" keyboards with any of the WSAD keys bound to a function. they keyboard i have now uses the number keys for f keys, but the row with the m key for multimedia.
