Friesians Online (Grand Theft Auto 5)

Hello, before to proceed with the problem, just apologize for the fact that if there was such a topic of discussion, I clearly it is not stumbled upon. Either not helped. My respects to you, for understanding.

In General.
Onboard FX-8350 4.0 ghz (Black Edition), 16 Kingston HyperX DDR3 RAM (1866mhz), 1050ti, win10. Of course in the single, all perfect, stable without change of the frame 63. The graphics settings to Very high, only the msaa inul due to the appreciable drop in FPS. The plane turned, because then horror as it jumps from 65 to 80, and it sometimes hurts the eyes. And everything is at maximum. With these settings I have great pleasure played it, up to one point. Until the launch of GTA Online. In General, 40-50 frames per casino, in crowded places, while driving. In missions more or less playable, but FPS jumps. I don't know what could be the problem? Reduce quality is not an option, already tried. With the Internet everything is fine, connected directly. No extra body kits for the type antivirusnikov and other background tasks I have. In the head no decisions have come apart from the banal reinstalling Windows, although I'm completely satisfied with this Windows (Corporate LTSC). What can help? Maybe there are some graphics settings for online mode? (by the way, nVidia Graf.settings default, but I don't think it will fundamentally change the situation, if I set the settings that so hard to offer Utara). In General, I hope that someone will help in finding the solution to the problem.
