Because they had a target when they developed their product.

And they stopped the optimization when the target was in reach.

You do realize what the target was?

(Less optimization = Keep more money at home)

The average calculator today has more processing power than a super computer had in those days. Anyone still claiming Amdahl's Law today as mattering to computing is justifying developer laziness and stupidity.

In 1967 they couldn't have possibly imagined the power CPU's and GPU's possess today. They couldn't have dreamt that the mobile phone of today would have hundreds, if not thousands of times the computing power their massive machines could muster. Even in the 70's when people were walking around with giant brick phones they didn't dream of having tiny little phones that fit right in your ear. You guys are desperately grasping at straws.
Stop being difficult and accept everyone will be better off using cpus with a single coherence lookup table.

Your head isn't made with a single coherence lookup table, so It probably means sticking to it is not the right way up to improve.

What makes the improvement per core weak nowadays is the tool used.

Our programmation languages were never really made with global parallelism in mind.

The next great iteration will come from it. So is the effort in Mantle/Vulkan/DX12. (because low level brings parallelism)

Biology is totally a different kind of beast, imo; however I'm open to hearing your opinion on that, too.

Low level doesn't mean parallelism, it means less overhead and more control. parallelism means you have two or more tasks that don't depend on each other for inputs, so you can do them simultaneously. That means identifying and serializing every possible situation where one of the tasks might require input from another, or where one task might change data that the another is using. The programming language doesn't really impact this, but the previously written code does(including the game engine, if the dev team isn't rolling their own). Also, the more different threads you split stuff into, the more signaling you have to do between them, and the harder race conditions are to accurately detect and debug.

At least oculus are doing the rational thing. Trying to maximize their profits and the expansion rate of VR by getting as many devs as easily as possible to the table.

Maybe it hurts some people in the short term that you're not recommended to game on an FX 8320+GTX 970/R9 290 combo, but oculus rather have more good games on the platform. Unfortunately, good games sometimes don't overlap with well developed games.

There's nothing wrong with only half the devs adopting the future of coding right now, which, to the creative parts of the industry, is really more about making more awesome games, with more complex lighting and draw calls, rather than optimizing for 8 cores.

If you're testing the water on the VR side, it might be handy to get a taste of Vulkan as well, which just released a couple days ago, so was unavailable to any prior development unfortunately, but you could also go at it from the angle to just make a visually basic (but good looking none the less) game, on Dx11 or something. Sometimes this might run on any hardware flawlessly, sometimes it might not!

Dismissing a factual and accurate mathematical model regarding the maximum limit of scaling given a percentage-based portion (completely negating any relevance of the speed of today's processors to the model) of parallel code which is still universally taught in basic computer science courses and remains, to this day, a very relevant model to illustrating the limitations of parallel computing basically because "ew, it's old":



CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 60




You argument is pitiful and it's clear how little you know on the matter if the best you can come up with is "relevant math computer scientists all know is bad because it's old". Talk about grasping at straws.

... I chose "brings" and not "means" for a reason bro smile.gif.

To all other posts that I'm too bored to quote, or to answer.. Guys honestly I could care less about Oculus.

I was just explaining why it would not support AMD hardware when we already all know it's globally less powerful than intel's one. I did not give my opinion on it, so I can't even understand how I get answers like "dude you got to understand it's a good/bad thing" biggrin.gif.

Biology may be a different kind of beast, It doesn't change the fact we compare more and more often what we can do and what a computer can do. I just read a few weeks ago something about storing a petabyte in the brain.

I also remember a movie recently released called "the imitation game". Remind me who are we imitating?

At least I brought a comparison in the bargain, I actually argued why it'd be better to improve performance based on parallelism; you brought your doctrine with a godwin point. "everyone will be better off using cpus with a single coherence lookup table."

Some of these people on these forums... I swear to god it's actually nauseating to read. If you truly believe that AMDs chips CAN'T HANDLE VR, you're crazy. I totally understand that Intel CPUs perform better, but in gaming, the performance in marginal at best. When you're running at a higher hertz, and require higher frames, the reason Intel is a better choice is because you'll get that extra 10 frames with the same GPU, and for some that can make or break an experience...

Regardless, to say AMD chips aren't capable is just an uneducated statement. You must truly not know what you're talking about if you think an AMD chip can't handle VR, and you should really stop posting... this forum has become to obnoxiously overwhelming with people who try to be smart by quoting articles throwing out random statistics and percentages.... all in the name of try to make AMD look bad...

AMD is beyond a viable platform, right now you can buy an 8350 and a 990fx mobo for 200 dollars... Pair that with a 980ti and you've got yourself an extremely capable base for a rig that can pump out 1440p at ease. Stop making them seem like trash... honestley

If it makes you sick, you should refrain from exaggerating other people's points. thumb.gif

Taking a hyperbole for face value is an exaggeration, and the overwhelming majority of comments didn't even go so far as to lend themselves to excessive hyperboles. You'll have a far more enjoyable time taking it easy. smile.gif
