Lag (Call of Duty: Warzone)

This was the same configuration, but stand Rx 460
Bought a new gigabyte super 1650. I installed the drivers, ran in 3дмарке and scored 3999 points.
Drove in furmarke, the temperature as stated, cpu z all the same.
* But that's just the same GTA V high and ultra holds only 40 fps +-, above did not rise to do and reduced settings and resolution, vertical sync is off.
* Went to test CALL of Duty warzone there is generally the problem... when setting the in-game Shader required to run the game, the game work blank screen without any errors, I had to go with grasimi several times and still have to wait for loading. The game set the recommended settings, but I lowered to make it easier to play, leaving only the need for the shooter. When the game is loaded everything is fine, 60+ fps, but when you start to play the fps becomes 30-40 and generally not playable, duck and even krasoti the game can.
I do not understand anything, watched a lot of tests/comparisons with my processor, well, people, everything was fine, stable fps and no lag. I have the same problem.....
* Here's a PC: AMD FX-6300
1650 GeForce GTX SUPER OC WINDFORCE 4G
kingston ddr3 1600 8gb x1

P. S please, write if you need anything else, logs/screenshots etc etc I do not understand
