Alot of these guys having problem how to fix the DOTA 2 low frames problem even the got an average or high end... will sometimes it can be solve by removing nvidia driver and some tweeks.. Solution No. 1 Look for new Updated Driver that suits for your unit. I prefer from Manufacturer site or Nvidia. Try to uninstall nvidia driver by going to Control Panel> Programs> Unsinstall> and look for nvidia driver.. restart the Unit Install the new Driver from Nvidia.. Restart and Finally run the Game.. Solution No.2 Disable the Vsync. - Vsync usually enable to limit the FRAMES of ones games... by 20, 30 and so on.. if you notice your frames running at stable 30fps, then you can disable the vsync. by the games option or from NVIDIA setting..
