WTF is wrong with multi-GPU support in games these days?!

By: Anthony Garreffa | Editorials in Gaming | Posted: Apr 5, 2016 12:16 am

We Need a Reason to Own Multiple GPUs; VR???


Alright, I've provided my case. Right now, multi-GPU setups suck. They're cumbersome, require too much configuration, testing, hair being pulled out - and most of all, money. Multiple video cards are super expensive, and with that money should come peace of mind - but it doesn't.




You spend more money, to spend more time, on an experience that should be better - not worse, where you're forced to disable one of your expensive video cards so the game will even work. Sure, NVIDIA and AMD sometimes have day one drivers ready for whichever game has just launched, but it's rarely perfect.



During my testing, I had countless problems trying to get SLI and Crossfire working in new games. Furthermore, I never received anywhere near 100% scaling - which is a huge problem. If you don't know what "scaling" means when it comes to multiple video cards, here's a quick lesson:


If you have one card, you'll be using 100% of your video cards available horsepower. If you add another card, you want to see another 100% being used (thus, double the performance). But, you don't - most of the time you'll receive somewhere between 20-60% scaling, which means you're getting around, and sometimes less than 1.5x performance - for having 2x the GPU power.


During my time working in IT retail, I sold custom gaming PCs for a living. I always said to consumers wanting SLI/CF rigs that they would be spending "100% more money on another video card, for 20-60% more performance" - which always had people thinking. If you're dumping another entire video card in the system, you system be getting another 100% performance - but you don't.


It's not perfect, and this isn't NVIDIA or AMD's fault - sure, they could help - but their hands are tied behind their backs, with game developers mostly at fault. Game developers - and I mean virtually everyone, you're all pathetic. You've sold your souls for consoles, and now high-end PCs are suffering - except Oculus and HTC are here to save the day with VR gaming. That last bit was a bit alarming, but this is how I feel.


Sure, not everyone has an enthusiast PC, but that's like saying that huge Hollywood movies shouldn't have the best special effects - just, cos. Alternatively, whinging because expensive cars are expensive. Enthusiasts are a huge part of the PC, and thus, they should be treated well with increased support for multi-GPU setups.
