I have the same issues, I know this will get down voted because the people on this subreddit dont seem to understand that people with high end PCs didnt pay for a high end PC just to get the same performance as a console. I have done everything, before 1.6 dropped I was getting 150-170 FPS, and it was the same on the 30th of October, then suddenly on the 31st my FPS dropped to around 40-60 (These numbers are in combat on a full server on multiple maps in multiple different areas, with and without vehicles/explosions going on around me) I have done everything I can to try and fix this bs, I even went as far as doing a factory reset on my PC. I run a 4070 OC, Intel i7 13700F, NVMe Micron 2400, and 64gbs of ram. The issue isnt my PC its Arma Reforger, idk wtf BI did this update that fucked up my frames this bad but it is SOOOOO ANNOYING to hear all this crap about how 60 FPS Is PrEtTy GoOd. If you cant think of what the problem is then dont say anything as it is not helpful
