How to remove microfreeze in games?

Question

Video cards

Hello readers of this post.
I ran into an unexpected problem. It consists in the following: when playing GTA V, microfreezes and FPS drawdowns began to appear, this appears at the moment when the GPU load drops to 0. I don’t know if the load schedule is somehow related to this, but nevertheless. Previously, this was not observed, neither friezes nor drawdowns in the GP. I tried to search the Internet for a solution to this problem, as such I did not find it. Also saw a similar post here GPU load jumps! (The load of the video card jumps in all games)?, but there the person was puzzled only by the load schedule, there was no talk of drawdowns. The only thing I did was set msconfig to use all 12 cores and 16 GB of RAM. In part, it helped, but only when turning on vertical synchronization, when turning it off, everything also draws down for a fraction of a second. The iron itself pulls, and I don’t even have suspicions about it. Average 150 FPS, shows in Radeon software. I haven't tested it in other games, but I think it will be the same problem.
Hardware:
Ryzen 5 3600, 16GB RAM, Sapphire Nirtro RX 590(8GB). Everything is stock, no overclocking.
I ask those who know to help. I can add information of interest. Look like that's it.

Logically, if there is a microfreeze and the load on the GPU drops to 0, then this is not caused by the GPU, but by the CPU, which did not have time to prepare instructions for the GPU. In GTA V, this can be, for example, due to the loading of world data from the HDD / SSD, i.e. the storage device can't keep up or the antivirus/firewall is slowing it down by checking the data that GTA V reads from the disk. Try disabling Windows Firewall and what kind of HDD/SSD do you have? Can it be heavily clogged or perform defragmentation on it?

If it's worth 10, you can try to roll back the latest updates because of them, some users experienced drawdowns in games.
