GTX 1080ti SLI

I am having trouble with 1080ti SLI, I have a HB bridge and a 1500 watt power supply and an i7 7700k (Z270 chipset) from intel CPU plus 32gb ram, my motherboard is an Asus Maximus IV formula which fully supports Nvidia SLI. If you look at the attached documents you can see my default settings for the Nvidia control panel as well as the GeForce experience settings and Nvidia optimized settings for GTA V. With these optimized settings I am still getting lower FPS and more stuttering that with a single card. can you help me out to change the settings so I can get smoother gameplay and higher FPS. I know I shouldn't expect double the FPS but I shouldn't be getting less FPS

Sorry, but some games do have negative scaling. Try turning off SLI.

This is why I stopped using sli. Support is dodgy at best. With only a handful of games that seem to even utilize it well. IMO at 1440p a single 1080TI is fine.

What about the settings in GTA V itself?

I used the Nvidia optimized settings for it. It's not like I'm using all the vram up either barely scraping 5gb

Tomb raider fully supports sli. If you want to test it check it out there first. I know the 1080ti has drivers problem right now with sli

2 1080ti are too much for even a 7700k, you're going to have to up the resolution to make use of them. 

If anyone asks you never saw me.

I ran a dual 1080 build for a while, and GTA ran fine on it for me

Not necessarily. It has 16 PCI-e lanes, and going from x16 to x8 on a gen 3 slot won't really cause an issue.

But the 7700k will. It's a bottleneck, there is no CPU that can beat 2 1080ti at anything under 4k. Has nothing to do with lanes.

No, it's not a bottleneck. It's a current-gen quad core with hyperthreading, it can definitely keep up. And yes, there are CPU's that can keep up, otherwise no one would buy more than one, yet people do. It has everything to do with PCI-e lanes, because that's how a GPU communicates with the CPU. They are like railroads to a train station. If there isn't enough track, only limited amounts of info can reach its destination.

Bro, please. It's a bottleneck. 1440 is low resolution when talking about 2 1080ti. You need 4k at least, i'd run 5k. 

 

This isn't a debate, this isn't opinion. At 1440 the 7700k is a bottleneck and causes issues.

Ok, bro. Continue on with your delusions.
