Dota 2 and NVIDIA Optimus (525M) problem
Manufacturer: Dell (Notebook)
CPU: Intel i3 - @2,1 GHz
RAM: 6 GB
GPU: NVIDIA 525M (1GB) / Intel(R) HD Graphics 3000 [Optimus technology]
NVIDIA driver version: 310.70
Dota 2 launch options: -novid -console
My performance has always been stable (almost one year) excluding the Frostivius event which dropped my fps significantly. Even after it has finished, it seems that my fps got lower and much more unstable than before. I tried almost everything known to man in order to improve my FPS and overall game smoothness. I usually run Dota 2 with all graphics turned either low or off and have only Render Quality on 100%. I experimented with turning Vsync on and off but it doesn't affect the performance since I rarely reach more than 60 fps anyway.
In one of my desperate efforts to investigate the source of the problem I ran the Nvidia GPU activity tool and it seems that Dota 2 doesn't trigger my Nvidia GPU but instead runs with the Intel one. I am not sure if it has always been like this or at a previous point Dota 2 ran with the Nvidia GPU. At first I thought that my drivers are not OK although I always update to the latest ones. I ran Mass Effect 3 to see if this game will trigger the Nvidia GPU and in fact it did. Here are two screenshots to see the difference:
I thought that my Nvidia Control Panel settings were reset/screwed up somehow but when I checked they were the same as months ago:
As you can see, the Nvidia GPU is forced to run Dota 2.
Does anyone have the same problem with the Optimus technology (400M/500M/600M series)? Is this a known issue or am I the only one who experiences this?
