question Fast Sync and Mobile GPus

[Ganondorf]

Hey everybody. Been searching around a lot for this and have not yet found a solution.

 

I think I have reached the point where I'm kinda sure it wont work but if someone has any ideas let me know.... or something I might have missed along the way.

 (Also be patient with me if my tech-vocab is off sometimes as I'm new to this)

 

So First off I have an Acer Nitro 5 laptop with the GTX 1050.

 

The goal here is to play Overwatch at a high unlocked FPS while enabling fast-sync to stop screen tearing. (As I used to do with my old desktop rig)

 

So the first problem here is that fast-sync was not an option in the NVidia control Panel.

Ok simple enough, lets download NVidia Profile inspector and force fast sync to work.

 

And it doesn't.... every time I would apply the settings and go check Over watch, the screen tearing would remain and when I refreshed NVidia Inspector, the settings on v-sync would be back to "3D Application setting"

 

At this point I realised that the reason fast-sync is not an option is because the onboard intel graphics are driving the display and the GPU needs a direct connection to the display for fast-sync to work.

 

Ok so lets go into the hardware manager and manually disable the intel graphics. Ok great that works but my GTX 1050 did NOT take its place, infact now when I try to open the NVidia control panel it tells me "this display is not being driven by an Nvidia GPU" or something to that effect. So the display is being run by something else entirely besides the onboard graphics or the discrete GPU.

 

Ok lets go into the BIOS and see if I can set priority of which GPU drives the display. Except there is nothing in the BIOS for such options. There is not advanced options and really nothing to tweak.

 

So at this point I am basically out of options. It seems that in my case Acer has hardwired the discrete GPU to simply not be connected to the display at all but rather interpreted by the intel onboard graphics.

I'm also pretty sure running a monitor FROM my laptop would not fix this either as the second monitor would still probably be run by the wrong GPU.

 

This is quite the rabbit trail and its hard to explain as I don't really fully understand whats going on myself. This is my best guess. But I know LTT forums is maybe the best place on the net to come for help and opinions. IS my theory that my GPU is permanently divorced from my display correct? Allowing no possibility for fast sync on the hardware level?

 

Finally does anyone know any other approaches to solving the original issue in the first place? In twitch shooters like Overwatch low latency is literally night and day. The difference between vysnc on and off is 16.2ms vs 7.2ms which in a fast paced shooter is a huge difference. Besides I've really chased this issue and I would like some sort of resolution.

 

So thanks again for reading and I look forward to hearing your thoughts.

The 1050 is connected to the display through integrated graphics on a hardware level. There's nothing you can do about this other than using Vsync and deal with the increased input lag.

The reason why I went for the Helios 500 instead of the msi raider. Acer disables the intel integrated gpu from factory and only enables in my case the 1070. As a user you cant turn on the integrated graphics too so I guess they disabled it on hardware level? Btw I think this was mandatory since my panel is a 144hz G-Sync panel and I dont think G-Sync would work over the integrated intel gpu
