Ok, I see now. I have x2 8 pin pcie cables already in the machine that are connected to my 3090 but the the x2 cables seem to have daisy chaining connectors meaning i can in theory plug x4 connectors into the supplied 4 way splitter? Is it ok to daisy chain (using just x2 cables each with x2 8 pin connectors on) rather than having x4 seperate cables?
I have a Corsair HX1200 btw.

i was advised on here to use 4 separate 8 pin pcie cables so that's what i'm going to do. in theory you could daisy chain them but i'm not going to risk it.

I have him blocked... please tell me he's now running around singing the virtues of DLSS 3 :cry:

PS: the best thing you can do for your sanity is click on his name above his avatar and click on ignore, there is something not right with him.

bingo... I think he needs his eyes testing, because i'm sat here watching this mess on youtube with their terrible 60 fps limit and image quality and can clearly see how broken DLSS 3 is even at 60 fps can you imagine how much worse in real it looks even at super fast frame rates, funny part on the HUB video Tim says it looks like a knackered gpu with artifacts and then says it's not broken the gpu and it's DLSS 3 doing it, basically warning owners if they see that their cards are not broken :cry: .. Because looks like a broken gpu with bad VRAM.

Undervolting looks great. you can achieve 98% of the framerate and top out at 300W.

I haven’t received my 4090 yet so can’t test. I am seeing some info online suggesting that reducing the power limit alone is a better option with these cards instead of undervolting.

Common. Hint, if its multiple people blocking one person, its usually a sign something is amiss with that person! ;)

The problem is AI technology is not perfect, it cannot accurately predict where the pixel go from analysing images that are no longer relevent, it doesn't know when its put those pixels in the wrong place because it only knows what a now obsolete image looks like.

"Augment and Enhance" is not a thing, it remains science fiction.

And this is the result.

Kudos to Tim for making a video about it, but how is this acceptable when its on an Nvidia GPU but the same sort of image artefact's aren't when its on an Intel GPU?

Nvidia can literally get away with just about anything.

They get away with it because as evident by this thread and the OCUK stock levels, people will buy it day one regardless.

What we know is that the 5000 series will be more expensive than these ones and again people will buy them day one regardless.

Its one to test. The German outfit tested just undervolting which until the power used dropped below 80% then there was xero decrease in fps. They were running at 360W instead of 450W.

In other reviews where they have just limited the power, there has been some falloff in framerate (albeit small) before they got to 80% power.

What you on about, that looks fantastic :cry: , looks like someone just jizzed all over it.
 
dlss3 looks a bit hit and miss right now. Seems to have a narrow window of when you'd want to use it. Enough FPS to not feel input lag, Low enough to not clip max monitor sync, works best in certain situations, can't have frame pacing issues as it'll magnify
 
Spent a frustrating couple of hours trying to get one yesterday, but no luck.

I've today received an invite from nVidia to purchase an FE via a link in Geforce Experience, so went ahead with that. I've received confirmation email from the retailer dealing with FEs that I should get it on Tuesday.

The psychology of all this is brilliant - I'm almost feeling honoured to have been allowed to spend £1,700 of my cash on a graphics card I don't really need!
