SLI/Crossfire and VR Support

[gaelvc]

Hello everyone,

Does anyone has an extensive list of games Up to Date (August 2020) that support SLI or Crossfire.

I would like to know the same for VR games.

Thank you !

P.S. I am considering Double GTX 1080Ti (I have one for the moment and I would like to play on a higher FPS on 1400p on Odyssea G7 or ~4k on Odyssea G9)

Pointless. Very few games support SLI anymore and most of that support was dropped long ago, many driver versions ago.

In the games you speak of, a single 1080 Ti should be fine for 1440p/165hz, however you will want a very strong cpu and at least 16gb of ram and at least one ssd. Not to mention Win10 64bit 1909 or 2004, along with the latest Motherboard bios and all the latest drivers.

SLI and Crossfire are dead technologies. Nothing supports it anymore and both AMD and Nvidia put little work in to it on the driver side.

Yeah, sli takes a decent ammount of work to get working these days, you would be better off selling your 1080ti and buying a 3080 when it's released 'soon'.

For the record, I run sli 1080ti's.

Ok, thank you for your feedback ! Good advice :)

FYI I have
CPU :i7-6700 K (overclocked to 4.5 GHz and very stable)
RAM 16 GB
2 SSD
GPU : Aorus Xtreme edition GTX 1080 Ti
Power supply 750 W (plenty of room for overclock I believe)

I room Doom Eternal > 120 FPS at max (but my screen is 70 hz max)


Question:

1) So might consider Odyssea G7 (240 hz) instead of G9 which I might not be able to max with my Desktop ?

2) Might consider a wonder G9 (near 4k resolution) with a better Desktop (I plan on building one in 2021 only with RTX 3000s) ?

Thank you

Your cpu is going to be holding you back more than anything else as games begin to want more cores and 4.5GHz isn't really an oc for the 6700k, isn't it 4.6GHz boost by itself? You should get that to 4.8GHz atleast.

Regarding refresh rates, unless you are playing professionally, you don't need a 240Hz panel, 144/165 is more than enough, as the biggest gains are from 60-120 than 120+

Thank you again for your feedback

In the other hand, what is your opinion on NVlink for gaming and VR ? Example : 2x 2080 Ti

nv/steam link or anything that needs to [capture -> compress -> transmit -> decompress -> display] will be 1+ frames behind the host and be nauseous for any vr viewer

may be ok for 2ndary cloned displays or remote playing, but not suitable for vr

My advice is to avoid multi gpu now, it isn't worth it, the one occasion it would be, is if you have a high refresh 4k display or one if those nvidia 65 inch 4k 120Hz tv's, as, if that's the case, money clearly doesn't matter, that's also the only setup that needs / warrants multiple 2080ti's.

As I also have a 2080ti, I can happily say, it will handle high refresh 1440p just fine and 4k 60 nicely, infact, I'm leaning towards selling my 1080ti's when the new cards come out and watercooling my 2080ti to replace them, then running the new card to replace the 2080ti in my couch rig, as that's where I am doing most of my gaming these days.

Pointless for gaming or VR, a single 2080 Ti is more then enough if you can afford it. Even a single 1080 Ti or 2080 Super would do just fine.

SLI, NVLink or Crossfire, whatever Multi GPU setup is very poor for a VR setup, let alone a gaming setup.

Don't get dual GPUs or multi GPU setups. Sure it looks nice but the issues that come with it are just not worth spending money for.

*Flashbacks of SLI issues I had with my 2014 Alienware 18 with dual 780Ms*

the only sli that really made a difference was with the voodoo cards
where each card would render every other line in the images
