opt out of steam beta. Go to change profile name and then follow the picture. Click account in top left, go down to beta participation and click the box that says change, then in the window that pops up click none. This will disable broadcast but boost fps a ton. The update switched some commands to be gpu heavy instead of cpu, so try putting the command -default into the launch options and see if that gives you more frames. There have been instances where having higher settings will give you more frames because it makes it more gpu heavy. If the second method gives you more just tweak your config for allow for higher settings and then remove the command. I personally am getting more frames than ever, 200+ at worst. I just did the first method.
