I seem to loose a lot more than 5 frames, maybe it's a percentage, I turned off the filters and my fps went from around 170 to 200. Sadly I don't think I could play without them now. Visibility and look of the game is so much better. Standard looks a foggy dull mess.
My frame rate is still all over the place sadly, some games my fps can drop below 100 and it stutters like crazy, but then I should next game it was over 160 again, without a restart or anything.
I had similar where I would lose up to about 20% of my frame rate just switching it on. Nvidia chat helped me resolve it (Now lose about 5-6fps when I have it on)
This is what I done:
Added game to program settings in NVCP then set power management to prefer maximum performance.
They also requested I set max frame rate to 1000.
Then in global settings set the following:
• Ambient Occlusion – Off
• Triple buffering – off
• Threaded optimization - ON
• Vertical Sync – Off
Then in Help menu on NVCP, Enable debug mode.
Go to windows settings->System-> Display-> Graphics settings
Switch Hardware accelerated GPU Scheduling ON.
Reboot
