Force 1440p on a 1080p Monitor?

post #1 of 30
Thread Starter 
My CPU is bottlenecking me in sleeping dogs. I heard that, in order to fix this, you can increase the resolution to 1440p or higher, which I can't do nativly as I am on a 1080p monitor.

Why does sleeping dogs use so much of the CPU?
Even on stock settings (3.9Ghz) , I see no gain in fps or a lower CPU usage compared to 4.6GHz.
Can I force a higher resolution?
If i can, will it cause harm to my hardware?
I can't afford a 1440p screen. biggrin.gif
Thank you!

Do you mean to "trick" it into thinking it's running 1440p?
I'd think that's the only possibility there (assuming you'd have to change a game file to do so), as the display wouldn't actually be able to do anything above it's native resolution.

Um, wait, How exactly do you hope to resolve a bottleneck by increasing the resolution?...

20 FPS with 100% CPU, 60% GPU is better than 20 FPS with 100% both.

If it's a CPU intensive game, upping the res wouldn't help.

A 3770k is bottlenecking you?
I don't believe it, probably just the port, need of a driver update.

^ Sounds most likely to me.
GTA IV still runs poorly on my rig, and I know I should be able to have it fully maxed.

^This. What's the point in forcing 1440p. That's pretty much identical to running Supersampling but with crapier results.

Your PC is fully capanle of running all games on max with 45 FPS or above, but Seeping Dogs I would guess is a bad console port. And no, you can not force a res that is higher then your monitors AFAIK.

Thread Starter 
Thanks for the help so far.
Sleeping dogs is heavily optimized for me, that is why i'm confused. It is also a AMD game.

Here is an example of my issue.
My settings! (Lowering AA and SSAO and removing Vsync gives NO fps increase at all!)

Fresh format, CCC 12.8, windows updated, chipset software installed.
Max out, 1080p, CF enabled (46fps)
In the same area with CF off, I get around 35fps.

CPU usage is above 50, which means it is maxing it out. (It would be on a 100 without HT)

Even with Vsync, the cards are running well below 99 usage so the GPU's are not the reason for the low performance.

Any idea on how to solve this?
