Multiple Displays Affecting performance

[Furbodo]

I plan on getting a second 1080p display for my desktop. Something just to hold all my apps like skype and steam windows while I play games. Or watch/listen to videos while I play. Will this dip my performance several frames per second? With my i5-4460 and R9 380 I get about 70-80 fps on high in GTA V, and 60-70 fps in Witcher 3 on high/hairworks off. Will running the display hurt my experience? Can I utilize my on-board gpu in my intel chip just for the second display to avoid it affecting games? If a second doesn't hurt, what number will? My full system specs are in my signature. Thanks in advance.

A second display won't produce any effect in game performance unless it is also running a game (or something else extremely graphically demanding)

I mean in theory it will add graphical load to your pc. As long as your not playing intense flash footage or cpu intensive webpages I wouldn't expect your performance to noticeably drop.

not a whole lot. If you want just use the igpu for secondary displays

Interesting topic .

 

I have a main 1440p screen and a secondary 1080p one ( gtx 760 gpu )

 

If i just play csgo on the main one and the second one is at desktop , i get about 350 fps ( if i remove second monitor i still get 350 fps )

If i play csgo on the main one and watch a youtube 1080p fulscreen video on the other monitor, my frames drop to about 200 .

is it plugged in into the mobo ? Aren't those ports disabled if you have a gpu ? any link to how to do this ?

Yes

depends on the mobo but you can change it in the bios

Here is a guide

 

1. unplug monitor from gpu

2. plug monitor into mobo

3. profit

Are you sure it uses the igpu and it's not just a passthrough ?

Wait.. is that a thing?

I'm testing with afterburner brb

Interesting thing .

 

When i watch a video in a browser window on my second(igpu) or first screen(gpu) , both the gpu and igpu show usage up to 30% .

When i start a game , only the gpu shows usage and if i start a video while playing the gpu goes to 80% and the igpu to abut 50%

 

Linus needs to make a video on this
