Hi Guys,

So I recently got a new laptop that has a nvidia GPU in it. So when playing games Dota 2 for instance I get like 150 fps and then like every minute or so I get a studder that brings down the fps to like 10 for about half a second.

I've read online that it seems there are driver issues with Windows 10. Anyone else experience this?

Another thing I have notice is when using external displays is that there is severe lag. My laptop has a 1080p display and when I plug in my 1080p LG with HDMI it's like a get 25% performance from my card. Being able to play Farcry 4 maxed out with the built in display becomes unplayable on the external display even at low - medium setting at the same resolution?

I obviously set Windows to only output to the external display to minimize the 2nd display affect that might hinder performance.
 
Which gpu, how much vram?

Install msi afterburner & riva tuner statistics server which is bundled with msi afterburner. Monitor the fps, frame time, gpu temp, gpu usage, vram usage, cpu usage, ram usage which you can also log to a file. See what all the parameters reflect when the fps dips & upload the log file for us to look at.

But before that make sure you have downloaded the latest drivers from nvidia, geforce experience can also update your drivers.

My only experience with fps dips are when I run out of vram but not sure if that is possible with dota as I don't think it's that demanding a game where you would run out of vram so it's probably something else.
 
Might be a silly question, but are the Nvidia drivers up to date/ I get an Nvidia driver update notification at least once a week.
 
Might be an obvious question, but most laptops are hybrids these days. Make sure you are running your games on the Nvidia GPU and not the Intel one? The easiest way is to right click on the shortcut, and select "Run on high performance" or something like that. I'm booted into Linux right now, so can't check.
 
Thanks for the replys guys. I am indeed running the latest drive. I checked again this morning. 361.91. My card is a GTX960 with 4gb vram. Geforce experience on mobile machines have a good way to add application that are always supposed to run on the dedicated card. They also state that when connecting external monitors they always run on the dedicated card no matter the application.

Edit: It's not RAM or CPU either. I've ran my games with the task manager open too. I never reach 100% RAM or CPU usage. (16gb ram with an HQ i7)

Windows power plan settings? Just started running a bit of a gaming rig again a week or so ago, and I was initially stumped by the erratic performance. Fiddled some with the power profiles and all the weirdness disappeared.

It's always set to High performance. I only use it on power saver when I know I have to stretch the battery a bit.

If you hook up the display via HDMI and then close the notebook's lid, the BIOS clocks the Intel integrated graphics down, and you get that choppy, unplayable framerate. Lenovo does this in purpose, both to prevent the notebook from overheating because the vent is closed, and because of how they've implemented the Optimus switching tech from NVIDIA. Even if it's not overheating, the GPU still clocks down once the lid is closed.

It's unfixable, and ridiculously frustrating. Sorry. The best you can do is keep the display open, but use the keyboard hotkeys to turn the backlight off to prevent distractions.
