I saw massive improvements (loading times) after installing it on SSD...
Have updated my chipset drivers to latest version, no improvement.
Reset BIOS settings (optimized defaults - no OC), no improvement.
Disabled HPET in BIOS, no improvement.
I can't figure out what causes the drop in GPU utilization.
I chatted with the AMD tech support for a while and different guys tried to figure out what's the problem. No solution found.
I still have no idea what's the problem. For now I turned off MSAA, set water detail and particle detail to normal to slightly decrease the fps drops. It's still noticeable but I can't find another solution. I may switch to zen 2 and an X570 soon... maybe that will fix it.
Im facing the same problem tried to talk with the rockstar support but they didnt really "knew " or could help . Im wondering if someone actually fixed it or is just a connectivity or something related with the processor (in Gta)
Im using a ryzen 7 2700 , i have 120 fps in the vynewood hill while looking at the city, when the hours in game reach 19:00 pm and the lights turn on drops to 50/60
