LOW FPS ?
Here is a solution i discovered from an earlier Steam post that works!

How To Fix Low FPS or Lag Issue In Kingdom Come Deliverance
The solution is pretty simple, you have to add certain codes in game launch option and it will allow the game to properly utilize the ram and reduce lag issue. You just have to add two commands on the basis of RAM you have in your system.

Low FPS fix for PC having 4GB or more RAM:
Right click on the game icon and choose Properties.
Click on General Tab and click on "Set Launch Options"
Add -heapsize 524288
The above option is also available for a system for different ram. The list is below. You will have to use different values on the basis of RAM you have in your system to reduce the lag issue in the game.
8GB RAM: -heapsize 1048576
12GB RAM: -heapsize 1572864
16GB RAM: -heapsize 2097152
24GB RAM: -heapsize 3145728
32GB RAM: -heapsize 4194304
64GB RAM: -heapsize 8388608
Add the above command on the basis of your system configuration and launch the game. According to the source user if the game is struggling for RAM allocation, by using the above solution you can double the game fps and it will remain near to constant. You can also read our guide on console command and cheats.

Also, IF you already have the command there to enable console then just make sure there is a space between them so the command line will look like this:
-devmode -heapsize 2097152

So those two commands enable console and add heapsize for my system which has 16 gigs of ram CLICK OK when done.

"heapsize" variable is from HL2's Source engine, it doesn't work with KCD's Cryengine.

Very ODD that my FPS has increased since using the command......

I personally don't see any difference, oathetic performance for the title of this price, still.

I don't understand how to do this. Could you explain it to me please? I tried right click on the following file:

...\Kingdom Come Deliverance\bin\Win64\KingdomCome.exe

I select properties and go to the General tab. However, I don't see anything that says "Set Launch Options." Do I have the right file, or am I making a mistake somewhere?

You don't go to properties and general by clicking on the desktop icon; you go to your Steam Library, Kingdom Come: Deliverance, Properties, General and it's the launch field at the bottom where you input the relevant details.

Incidentally though, if you find that this method doesn't help with low FPS, I know a couple of other tricks that might help but you may not like them.
