FPS drops on gtx 970. Patch?

Actually it says that the oldest driver that the game can run on is 384.94, so going to try that one. You can find them here:
http://www.nvidia.com/Download/Find.aspx

384.94 was a bust, the stuttering was much worse. So I will go up from there build by build to see if is fixed somewhere. If it is not fixed anywhere, it may be in-game setting issue. Because some players with high end rigs can play fine as I've heard.

Tried again with the 388.00 drivers, with several "tweaks" on the installs themselves (the usual not having geforce experience etc) and still stutters. Closing in on the 10 hours of the trial now so think I just have to sit on the fence now and see if anyone finds a workaround or there comes a patch/hotfix for it. Kinda makes me sad cause was looking forward to playing this game :/

Do keep posting updates with your findings tho @Dryminator, hopefully you have more luck than me!

No luck with these drivers. Currently testing 387.92.

385.69

385.41

385.28

384.94

So 387 was a bust as well, no difference. Best performance by far with 388.13. Now I will test using in-game settings and editing profile if there is anything that would resolve the stuttering. I am running the game on Ultra at 1080p with absolutely everything maxed and doing the DB11 mission (intro second mission I think). Will update this thread on the go if I manage to pull something off.

I am running it on i5-3570k, stock speed; GTX 1070, 16GB DDR RAM (dont remember the speed), Windows 10 64bit

When it is not stuttering, the game is running at a solid 80fps, so my specs are totally fine for Ultra.

Yea it runs very well here too on Ultra, except when it stutters. Got i7-5280k and 1080 myself so to me it seems like the problem is game related and not on my end. Seen some mentions about the devs testing stuff that will improve overall performance but not sure if that was for PC or console, would be nice if a person from EA/this site could give a little wink about the issue being adressed or not :/

@LurkerYunOk so I think I found the main culprit for the very heavy stuttering. It is Ambient Occlusion... of all the things. It does something with soft shadows and the HBAO, AOA and AOA Full completely destroy my playing experience. SSAO is pretty much perfect, I get microsecond stutters from time to time, but those look more like lag that actual stutter. I would not suggest using OFF, there is not much difference in terms of performance and it completely removes soft shadows, making many things look... strange.

Anti-Aliasing change between FXAA and TAA did some minor changes as well, but it looked not to affect stuttering, simply FPS and therefore lag in places where there was more to render.

There is no difference in terms of performance between All Settings at LOW and All Settings at HIGH. And almost no difference in terms of quality HIGH compared to ULTRA, but there is a slight performance drop.

So what I would suggest to try is:
Everything HIGH
Fullscreen ON
Vertical Sync OFF
Motion Blur OFF
Ambient Occlusion SSAO
Anti-Aliasing TAA

Driver 388.13.

See if that makes the game playable for you.

Please note though that my test only involved the first minute of the DB11 mission until the end of first speedtrap/zone.

I'm seeming to have the same issue here and I honestly think that the first patch to the game made the stutters worse but I mean the game runs fine on ULTRA but that's when it's not stuttering which is every single second and sometimes it literally crashes my windows process completely. I just hope it will be an easy fix I'm just going to wait for them to come out with an update that fixes it. I just hope it will be soon.

Trying to play since day one, and this issue still persists. Too bad...

It is not the hardware for sure. I've got a lot of stuttering with 1080ti. ☹️

Tried your suggestions now @Dryminator and still stutters that affects the gameplay, think im just gonna have to put this game on the shelf for now untill they release a patch/hotfix for this.

Quite annoying tho that no official representative can give us a little info about if this issue are being adressed or not...
