Make it SLI compatibel

[Mark]

Hello! I have two 3D-card GTX 1080. One GTX is 8 GB Video Ram but I have two. That will be 16 GB Video Ram. But Far Cry dosn't support SLI. So I can only use one 3D-card. Please make it SLI compatibel

1. Having two cards with 8GB of Vram doesn't make a total of 16GB of Vram when both cards are used.

2. Not many game engines are SLI compatible as such a low section of PC gamers use SLI so its not worth the money to develop for it.

I can only use 8 GB VRAM when I have connected to SLI on Far Cry 5. Every game I can use more than 8 GB VRAM eccept Far Cry 5. Max Payne 3 I use 11 GB VRAM and GTA V I use 13 GB VRAM and so on

I can get a playable frame rate with everything maxed and 4k resolution with a single 1070....SLI is completely unnecessary with this game. Hell, I play on 1440p with ultra and get 60 to 70 fps .

It doesn't work that way. The 8GB on each card mirror's each other is all. So if you have 8GB VRAM in use while in SLI then all 16GB is being used, both cards at their limit, it's just that they have the same thing in each cards VRAM.

Some games may just use some silly math to acknowledge both cards. Like the if Max Payne 3 says 11GB then I'm sure it means 5.5GB on each card is in use and they double it to try to help people that do not understand how it works. I would not get worked up about it at all.

I think there was the possibility of DX12 allowing totally different VRAM usage and possibly adding different cards able to be linked together. Not sure where that is at, or if it would even work on existing hardware though.

The benefit of each card having the same thing in memory is that it makes it super quick, no needed memory swapping when going back and forth through whatever it is rendering. May seem wasteful, but has the benefit of speed.

And as poster below mentioned, I was pretty sure it does support SLI and even mentions it on the store page...

Some people are running tha game using two video cards.

SLI is fully supported and working well with this game. VRAM does not stack with AFR or SFR but I do believe it stacks with DX12's EMA. EMA is technically not SLI though, so I suppose it doesn't count.

I don't know how it work I just telling you Max Payne use 11 GB VRAM. I can send you picture if you don't belive me. I can touch of the Waterforce Fans of my 2 GTX 1080. The one will be warm when it is in use and the other cold. but when it is use more than 8 GB then the boths works and then the 2 is warm. I have two Gigabyte NVIDIA GeFORCE GTX 1080 Waterforce with 8 GB VRAM each.

I mean Max Payne 3 use 11 GB VRAM when you take maximum resolution and maximum effects on that game

Therein lies the problem. You don't know how it works.

1. VRAM does not stack.. and never will. Some game menus will show that you have double VRAM, but if you fire up Afterburner's OSD (or Precision X) you will find that your VRAM consumption will never eclipse the 8GB available on a single 1080. This is a coding issue within the game's menu UI that is reporting incorrect resources.

2. The reason for the temperature disparity is either due to:

a. Card location - the bottom will naturally run hotter if you are using an open-air cooling solution as the top card blows hot air on to it causing that card to work harder.

b. Utilization - You will never have perfect scaling across both cards. One will naturally work harder than the others. Even this will vary from game to game as some profiles are more efficient than others.


Please stop arguing with us. This game fully supports SLI. Make sure your drivers are up to date.. the Far Cry 5 profile was included (and updated) in the previous two releases.

I know you don't want to hear this, but dual GPU is dead. Few devs support it, the card makers themselves barely support it, and it's a constant hassle of bugs, driver issues, and just flat out disinterest from the game devs/nvidia/amd.

Get a single, powerful GPU. That is the solution to your SLI support problem. I learned this the hard way via three straight SLI rigs from 2009-2014. So many "AAA" games just stopped even caring. Non-stop support issues. I was on the forums for SLI more than I was actually gaming with my dual 460s/670s etc.

I both agree.. and disagree.

The days of "plug and play" SLI are definitely waning. A few years ago it was much less work to configure a profile to gain some extra performance.. but I find myself spending much more time now'a'days.

That being said-- as a software engineer I love the challenge. The price of a second card is always worth the "hassle" if you don't see it as a hassle. Plus, two cards just look cool :)

I've always maintained that SLI is meant to take two powerful cards and try and squeeze benchmarks and games to performance that doesn't currently exist on the market. Using it for anything else is definitely a losing battle.

As far as i know the latest drivers have sli profile.
