Frame loss in games when using second monitor?

[tom.dolan321]

I've recently got a second monitor and now in titanfall 2, whenever i click on my second screen, the framerate drops from around 55 to 15/20.
more recently, it been starting up at 15/20 fps.
Also when this happens, the resolution looks bad too.
I'm assuming its not a problem with my gpu as it runs perfectly sometimes so it must be powerful enough right?
Gpu: AMD radeon r9 200 series
Cpu: intel core i5 - 4460
8gb memory
using 2 1080p monitors
Thanks for any help

right. it is not strong enough to push 2 screens. that's double the pixels every second it has to produce. of course it will effect overall fps.

you're seeing about half the fps which is right on what should happen when you add a second screen

But it runs fine with both monitors in use sometimes. When it works it works great and then it just drops, there's two monitors plugged in the entire time, even when it's working fine
I'm only playing on one screen and browsing on the other if that helps

without knowing what game you're playing, i am going to assume that once you get a game that taxes the gpu to the max, this is when the second monitor is a liability and effects performance a lot.

other games that may be rather light on the gpu, may be ok with the second screen running. the r9-200 series is simply not designed for that type of work. i have an r9-270 in an older pc as well and it'll run dual monitors fine, but i've never tried gaming and browsing at the same time on it. normally it's just a movie to one screen and browsing on the other or other light weight work.

Dual monitors isn't an issue for any gpu. You can run dual monitors from any igp/APU easily enough. I game on an old 660ti, running dual monitors. Video/wiki/Google etc takes next to nothing.

That said, using Eyefinity or nvidia Surround to Game on both monitors is a killer. Games graphics are extremely intense to the gpu. You effectively double the demands as resolution goes from 1920x1080 to 3840x1080.

You'll also find that Win10CE has drivers issues. Bios, Lan and audio drivers are constantly being trashed, dropping fps hard as legacy drivers are put into loops, trying to be over-written by newer windows generic drivers. The mobo drivers need to be checked for vendor patches every so often, especially after any windows updates.

When the game is no longer the focus window, the GPU will throttle back as the game is now "running in the background". Perhaps there are power management options that can change this behavior but I haven't looked into it much.

I'm playing titanfall, I could run it at high settings with good framerate before but the problem continues with even when I drop the settings to low

That sounds like it could be the problem, ill do some looking into it tomorrow, thanks. P.s. i didn't mean to give you a -1 sorry
