NVIDIA SLI Compatibility Bits

[SingleMaltScotch]

I've got such a backlog of older games to play, that I haven't bothered to build a new system. As such, I'm still on an i7-6700K @ 4.5 GHz, 32 GB RAM, 2x GTX 1070 (SLI) on water, 1 TB SSD (RAID 0). Honestly, it still runs most everything on high-to-ultra settings at 4K (I'm not a stickler for FPS, if it's at or equal to 35 FPS, I'm good). System is about equal to a 3070 TI when everything is working well.

However, my wife really wanted this game so I bought it and lo and behold, no SLI support -- which isn't too surprising since it's dead. I've found workarounds and NVIDA Inspector bits to use in the past for a lot of games, but after many different profile attempts and about two hours of tinkering, I still haven't come up with anything that will force Hogwarts Legacy to recognize and use the second graphics card.

I'm able to pull down ultra settings at 1080p, but I could probably get 4K with high(ish) settings if it could use SLI.

So... anyone know of any tricks or have any compatibility bits to get this game to render in SLI mode?

SLI support has been mostly dead in modern games, I believe it's deprecated.

SLI is dead. Nvidia doesn't support it anymore.

dude buy a new pc already

SLI has been dead for years, most games do not support it and if they don't you're only using 1 card.

A single 1070 is not anywhere close to a 3070ti (quite frankly neither is two 1070's in SLI)

nvidia ended SLI support 3 years ago in 2020:

Unless a game was in development prior that with plans to already use it, newer games no longer do since they can't get nvidia support to implement it

I know SLI is "dead" -- I said so much in the post. I'm not buying a new PC when I can still get high-to-ultra settings, even if I have to drop down to 1080p. The 4xxx series is a joke, and am waiting until the 5xxx series (hopefully chiplet design).

I just would like to know if there is any magic sauce out there to force SLI AFR. I'm not a compatibility bits wizard, so maybe someone has something that worked for them!

SLI is dead and literally not even a single devs been supporting it even since it was even supported it was supported by GPU devs. It is dead they wont do nothing about it.

I feel your pain man. I used to run 2 970 in sli and when it worked it was absolutely fantastic. But the hours in my life I've lost with finding proper SLI bits and various other settings I can never get back and hated every minute of it.

yes, it's hilarious how much weaker the 1070 is

I would direct you to this video:

With the heavy overclock I have since the cards are on water, I am indeed close to pulling down stock 3070 Ti numbers when SLI is working well.

I can tell you right now with your setup the best you should expect is 1080p (not 4k) with high (not ultra) settings.

There's no point in arguing beyond that, you clearly don't understand what's involved now that SLI isn't supported by nvidia anymore

I'm already playing it with ultra settings at 1080p. You lack reading comprehension, as I already stated as such. I do not need to be told about SLI -- I am well aware of its current and future state. However, a number of people have found ways to get even newer games to recognize SLI through compatibility bits.

You obviously don't have an SLI system, nor probably ever had one previously. So you really can't contribute anything here... so why are you here?

Every time anyone with NVLINK/SLI asks this question on the steam communities forum, to see if there's someone out there that's got inspector bits working for a given game, the troll patrol piles on to remind us what "know nothings" we are for trying. Don't feel bad, these people have nothing to contribute to the discussion but like making noise and undermining others.

We all know the technology works and it's great. Unfortunately, I haven't found a work around in this game either. I haven't bought it because it doesn't support NVLINK, but I am tempted. I hope someone will find a work around or the game will get an update to improve it's scalability in mGPU.

I can't wait for ray tracing to die the same way. It almost never works properly, which to be fair is on the devs shoulders more than Nvidia.

I found the last 3 nvidia drivers break sli in alot of games.

Greetings, good man!
Please tell me, have you found a solution on how to run Hogwarts Legacy in SLI mode?
