Question DOTA 2 FPS Drops

[saxer]

Hello,

I've got an issue with DOTA 2, the game runs at about 70-90 fps, and then in teamfights I get drops <40.

PC Specs:

GA-990FXA-UD3-rev-1.2 (i don't think it can run more than 1600Mhz RAM)
AMD FX-6100
2x4GB DDR3 (1600Mhz)
GTX 1060 (3GB)
SSD (Windows and DOTA are on the SSD, Steam isn't)

I though the issue is with the CPU, as it is old and kinda bad for games as far as i know, so I OCed("stable", 30min prime95 @ 69C) it to 4Ghz, which resulted in lower CPU usage, but same framerate.


Here are some screenshots:

- Stock CPU, no Vsync, almost everything on high, except for water, dashboard, etc.

- OC @ 4Ghz, everything on high, no Vsync, Chrome Open

- Same as above, no Chrome

- OCed, lowest setting possible

Dota is ran at High Priority.

I also ran it @ 1280x720(lowest settings), FPS was about 42-44, but couldn't screenshot it.


So, am I RAM speed bottlenecked? I don't suppose increasing ram will help, as Chrome opened/close (~500MB RAM) didn't make any difference? Idle Windows 10 runs 2-5% CPU, updated BIOS to the latest possible, ram is in correct slots.

Any ideas how can I increase without changing mobo and CPU?


Thanks!
