I purchased a GTX 1080 to make my games look pretty. I got especially excited to play this game on ultra settings. I fired up the game, and the performance was rather choppy.

What a disappointment.

Any ideas on what could be causing this?

Specs:

i7 8600k
GTX 1080
16 gig ram
running 1080p

Thanks

I too have an gtx 1080( + cpu i7 8700) on 1080p, and it is running ok, in worst case you will need too re-install the windows, but did you put the last nvidia driver?

Yeah, I agree with pigulici: this is not a card issue, this is a system issue, meaning something on your system is slowing performance and that needs looking into.

Without wasting your time and making useless posts like others >.>

I had a similar isue after a fresh install of system/gpu, it was pretty simple actually, I noticed on control panel the gpu performance was set to adaptive and I changed it to maximum performance, that made the difference.

Whereas your post is a panacea and guaranteed to work in all circumstances. Congratulations.

By any chance, is the frame limiter on in The Witcher 3's graphics settings?

you should spend more time on playing the games so you have the knowledge necesarry to help the players with certain issues, instead you are kind of a leech with only 24 hours spend on all the games on ur profile, the only game you have experience with over 1k hours played is the forum game where you have hundreds of useless posts gg

334 games = 24 hours spend playing all of them, you are some google bot or what lol, shame on you dude for pretendting all this years on this forum you are some big shot, but now ppl can see if you really played witcher 3, and you didnt... its impossible to even finish the full velen questline on 24 hours that is if you dont rush it, but that would be pointless right from a guy that made hymself the image of some big shot that has a vast experience on games he play, giving stupid and fake useless advices here and there, but the real truth is you'r knowledge about witcher 3 is no more vast than Radovid flacid c0ck, Kalkstein told me.

You are so funny... not.

Graphics cards are a bit of a tricky issue, especially with somehting like Witcher which needs so much GPU power.

The 1080 is the most powerful graphics card around that the moment. https://www.tomshardware.com/reviews/gpu-hierarchy,4388.html

This is however, a hardware issue, not the software of Witcher 3

Make sure you don't have unnecessary programs running in the background. You can look at Task Manager to check. Right click on your task bar and select task manager. If you have things starting up that you don't need, use Ccleaner to stop them.

Make sure you completely uninstall the previous drivers. Clean install.

This may seem counter intuitive, but try reducing some of the demand.

You get the biggest meanest graphics card available and thing you can ramp up everything. But much of the power fo that card is not necessarily intended to be used for this situation. The Oculous Rift for example, might thank you but Witcher on a monitor is a bit like bringing a double decker bus to a prom date.

Go into Options and turn off all the Post Processing options. None are really needed. See how thigns work from there.

If you are still having problems

In Graphics, you will probably want Hair Works. Personally I have it turned off, but for those with good eyesight it will make a difference.

Other options to look at are quality settings. Crowds set to high makes little difference to the game but a lot to the hardware load.

and on first disable this fuking meltdown patch :) i can t post link but on youtube write Disable and Enable the Windows Meltdown Patch the first video is good on the channel RyuConnor
