NV Link results?

[Zberg]

Anyone have much experience with NV link on the RTX cards?  What kind of scaling are you seeing?  If I can get another awesome deal on an RTX 2080 or if they come down in price at all that may be the route I go, unless NV link sucks.  Though I did have great performance scaling on my previous 970 SLIs, so maybe with the higher bandwidth it'll be good?  Curious to see what people have been getting.

just youtube it. I think NVlink is better than SLI

support is still literally SLI on the software end, so anything that worked with SLI on previous cards will still work with Turing cards + NVLink.

 

I believe GamersNexus did a video where they mentioned this (not sure if it was specifically only about this version of NVLink), but as far as my own use I haven't noticed any difference regarding the scaling. It does have much higher bandwidth than the old SLI connector so in theory that should help but I never noticed any stuttering anyway with my Titan Xp SLI setup (in games that actually used both cards).

 

Now with Titan RTX NVLink SLI (say that 10 times fast), still don't notice any.

Ya in doing some searches I was getting excited with one of the videos showing 70-80% scaling (would far surpass a single 2080ti), but I also found a couple articles/charts with essentially 0-5% scaling in a couple titles (clearly no SLI support in those games!, would be worthless) and the standard 30-50% in others.  Honestly if I could just get the same scaling I was getting out of my 970's, the value would more than be worth it if I can find the second 2080 for low 600's.  I've got a buddy who is fortunately going from 2080 to 2080ti and is looking to move his 2080 quick, so I might just pull the trigger on that.  Maybe I'll update this with some numbers if I go that route so there is more data on it...

 

...Unless I get 10% scaling in all games...then I hang my head in shame.

Yeah as usual it just comes down to the games you play. Witcher 3 has nearly perfect scaling, but I've been having a weird issue with it for about 4 months where after just a few minutes of playing the display freezes but the game continues to run for a few minutes (I can hear the audio, and if I move around I can hear Geralt walking around etc) before completely crashing/disappearing putting me back on the desktop. This happened on my older HEDT with a 6900k + two Titan Xp and still happening on the new one with 7960x + two Titan RTX.

 

The other sad story is World of Warcraft which unfortunately now is better in DX12 mode which can only use 1 graphics card. SLI will still work and scales about 90% if you run it in DX11 mode but last fall they decided it would be a great idea to remove explicit full screen from DX11 (which is really what you needed for good framerates especially with SLI) so now your choices are SLI but lower fps in DX11 due to forced full screen windowed borderless mode, or generally slightly higher fps in DX12 mode but only 1 graphics card.

 

Battlefield V in DX11 (with the SLI profile manually created) scales pretty well too but no DXR or DLSS if you are not in DX12 mode... and I can still hold above 100 fps with a single card with DXR enabled so it's a toss up.

 

All in all I wish 2 things would take place across the board - DX12 has a multi-graphics card component in the API that devs can use but to my knowledge none of them have used it yet, so I wish A) Microsoft would make that more appealing to put into games, and B ) including DX12 multi GPU would become a standard thing (again hinging on it being easy enough to implement basic functionality for). That way those of us who want all the frames can have them without making the experience of folks who only have 1 graphics card poor or unplayable.

Update: 

 

Got the second 2080 for 550!  Just hooked it up and ran SOOTR benchmark and jumped into the game with it.  Benchmark got an 80% scaling increase and getting a NICE smooth 144hz+ in game at 1440p.  Just moving the camera around is so satisfying at a true 144hz.   Could not be happier, not getting any glitchyness yet.

 

Going to benchmark my other games later on and see what kind of scaling they get (Wolfenstein, fallout, GTA, Metro Exodus).

 

Will see what happens with Anthem tomorrow as well (launch day always goes well right?!)

Another update:

 

Anthem seems to have OK scaling.  After watching a few people's 2080ti results, I compared to my own 2080 SLI.  I have a slight advantage over the 2080ti without any issues of stuttering or glitchyness (which I had heard a lot about, maybe they patched it before it went live?)

 

I am sitting in the 110-120 range running around fort tarsis, and the 80-100 range in combat.  Minimum rates rarely drop down in the 70's when crazy stuff happens (explosions all around me, surrounded my crowd of enemies).  Not quite the scaling I wanted, but still looks and plays extremely smooth.
