I had a drop when .62 came out but it was stable up until the patch that came out the end of June/beginning of July area, then it seems each patch since then it has gotten worst and worst. Each patch seemed to take 5 fps off, so I uninstalled the game and deleted the file you mentioned as well as the file in steamapp folder and did a reinstall and it only seems to have made things worst. I do run everything on very high settings but that is because I stream it and want it to look good but these are the same settings I always had so that should not be the issue. I did do a test and even if I put the game on very low settings I only seem it gain about 10-20 fps so there is not much of a difference in fps from very high to very low even though you can see a big difference, that is just weird.

*Update, turning on vsync does nothing, if anything I get more fps with it on but my monitor is 60hz and with vsync on it is still around 100-120 fps which is the same as it is when it is off. so something is really going on.

Thank you theclassifiedrebel.
Were there any updates to your graphic drivers prior to the issue occurring? And are your video/windows drivers up date at the moment?

I am not sure if I took a driver update prior but up until today I had the latest driver (see they came out with one yesterday that I have not installed yet). I have gone through device manager and manually clicked and checked for updates to pretty much everything. Not sure if it is a windows 10 creators issue or what is going on.

**Update, just installed the latest nvidia driver 385.28 and still has the same effect, vsync does nothing (not even limiting fps to monitor refresh rate).

I also had someone in my chat say that have been having the same issues but theirs is pretty much unplayable so I told them to post in here in-case they have other info that I do not have or can not remember. But I was in Novaya Petrovka Police coming from Zaprudnoe through the fields and I will getting 20 fps and then cam out of police to head to Sinistok and was getting 70-80 fps. So I am not sure why there are fps drops and select locations since I get the same thing running in the middle of no where.

Thank you theclassifiedrebel.
We are aware of fps drops in specific areas of the map and the issue is being worked on. However, the overall fps drop you have mentioned in the original report appears to be a different kind of issue and we will appreciate any additional information which could help us to resolve the issue for you. By the way, do you experience this issue on both 64 and 32 executables and on both stable and experimental branches?

ok here is what I came up with, Note: it looks that exp and stable have the same version but the exp test was done on an exp server. I did the exact same position standing on top of Gorka Police station if you go straight out the top the the railing and look down to the middle of the city so that I could get the most consistent numbers.
Stable test
*Rain
32-bit – 65fps
64-bit – 75fps
*No Rain
32-bit – 100fps
64-bit - 104fps

Exp test
*Rain
32-bit – 76fps
64-bit – 80fps
*No Rain
32-bit – 84fps
64-bit – 90fps

All test are in 3PP, if I go to 1PP I seem to get about a 20fps gain

Just in case you see something that I may be missing

Is there any other info that is needed?

update. I did have a file fail verify integrity and it has been fixed, but did not change the low fps

Great. Happy to help, just let me know if you need anything else. I would figure it would probably run better being on the same engine, lol. But yeah really looking forward to .63 and seeing what everyone has been working so hard on. Cheers
