Yes, I understand, but I still suggest that you update your graphics card driver… and there is a light on the card that indicates various warnings, check it too… I have an RTX 2060 and my friend told me that the light near The 8-pin cable is there to indicate hardware problems, although it depends on the color of the light
Most likely, you are right, the problem is with the game and the new update, but to be sure, check the items and test in different games.
gpuz is a good program, check there too, maybe it will tell you the amount more precisely
Good luck
