Severe drop in frame rates and 140 ms ping

Hello everyone, since the most recent update, my PC (which uses a geforce rtx 4070) and can typically run many games at a couple hundred fps per second and warthunder around 150-200 fps, can no longer do so. Despite not changing my graphics settings at all 80 fps is the highest I can obtain since the 9th wave update. Additionally, for seemingly no reason on certain maps, my frame rate will drop to 20-30 fps, which makes the game unplayable despite having a good gaming PC. This is combined with my normal ping of 40 ms frequently spiking to 140-150 ms. Has anyone gotten similar issues recently and potentially have any fixes?
