AMD Talks GPU Gaming Physics

For a brief moment, it once looked like hardware-accelerated gaming physics had the potential to transform PC gaming's static rooms full of storage crates into dynamic worlds full of showering particles, rumpling cloth and realistically collapsing bridges. Co-founded by Manju Hegde, a new start-up called Ageia ambitiously launched its dedicated PhysX accelerator; a technology that's now a part of Nvidia's family, and it looked like gaming physics was about to completely overhauled.

Honestly, complex physics is pretty invisible to the typical gamer. Accelerating it in hardware isn't all that useful, because the real expense of physics comes with sorting the bazillion objects you want to have in the world (sorting is NEVER cheap), not doing the accelerated precise collision mechanics.

About the only thing hardware physics gives us, is the ability to run a fancier simulation on a zillion small, simple objects, in a restrained space against a few more complex geometrical objects. That way you don't need to sift through piles of data to find what you want to collide against, and hardware can do its thing -- be fast without memory issues getting in the way.

In short, about the only things hardware physics are useful for are things like more accurate smoke, sparks, etc simulations. Constrained, compound objects like ragdolls become exponentially expensive as you attempt to make them more complicated, solve motor chains, etc. While it seems clever to throw hardware at this, really the end result is that you end up with wildly variable hardware physics performance, and you just end up having to limit the physics you use anyway, so you don't have performance spikes.

It's not like graphics. It just isn't. Physics is too variable / unpredictable to rely upon hardware acceleration to yield much improvement, relative to its cost. Game devs keep it simple because it not only performs better (HW acceleration would improve performance), but also because it just plain works better when its simple (hardware acceleration would not help make simulations more robust, relative to their complexity).

You can model a bicycle as a box, or low-poly mesh, and wrap an 11-body ragdoll around it, and have it be fast, and work. Or you could model it as a 10000-polygon mesh, and wrap a 45-body ragdoll around it, and have it be fast (with HW accel), and totally whacked out and busted (no matter what you do).

When does this end? Its killing everyone. Consoles and PC. And for what? AI? The benefits of AI are completely outweighed by the negatives. And the government should have never allowed one company to buy up all the RAM.

Lexreborn28d ago

This kind of proves this is an after thought product, most products like this are in r&d 5 years before they start mass producing. So they typically have the cost of components and things worked out long before assembly starts.

This is an assumption still, but I wouldn’t be surprised if project helix is similar to Scalebound,perfect dark and sod3. They had an idea but no actual execution other than concept stage. Being impacted by the ram shortage likely would also put this device 3-4 years out.

I’m not even sure MS has that endurance with Xbox yet

Fishy Fingers8d ago (Edited 8d ago )

I mean.... what?

We're at a point that Samsung wont even provide their own phone department ram because they can sell it at higher prices to 3rd parties (AI). Its more profitable to sell the ram than make their own devices with it.

You think because R&D starts 5 years ago the 3rd party component manufacturers will honour that price? They'll sell it to whomever is paying the most today, not some gentlemens agreement they made years ago. AI farms will buy more volume at higher prices than any console manufacturer will. It'll be the same for Playstation.

Lexreborn27d ago

Contractual agreements are not the same as “gentlemen” agreements. If you think that they work with their distributors a month before production then their entire business model is trash. They work with companies like nvidia constantly for building the graphics cards they need. They work with companies that build motherboards years in advance. This is what proper business planning does.

They are not buying components on a whim like a consumer. So again, considering the ram isn’t a singular module and is integrated into the motherboard I highly doubt they wouldn’t have a final schematic that they are supposed to be building around.

If they are delaying production another 3 years then it’s obvious again this is an after though project and is just trying to be responsive to their bad execution they had the last 14 years.

It also isn’t far fetched to use their failure to produce first party titles the last 7 years including the highly anticipated games I mentioned all being cancelled. That they would continue to you know… lie

Sitdown8d ago

You don't really know how this works huh?

Profchaos8d ago (Edited 8d ago )

Helix is going to be stupidly expensive

Instead of leaning into smarter upscaling techniques they're brute forcing hardware that will cost them dearly and it remains to be seen if it's genuinely going to provide a meaningful differential

I know in the oc.doace people like to brag about not using frame gen or dlss to get to high on a game but for the majority of players they happily use those technologies without a second thought

That's going to be ps6 vs Helix

Eonjay7d ago

Yeah with FSR 5 they should be able to offer a much cheaper version of Helix.

Eonjay7d ago

While this does seem to be the case, I am encouraged by the statement from Microsoft about wanting to provide affordable options. If this means a Series S style Helix, at least there will be something affordable being offered.

XBManiac7d ago

Series S is what has killed Xbox Series so... Will they dare?

blacktiger8d ago

It's called systematic inflationary. Yes we get it Microsoft, keep raising in the name ofall kinds of stuffs

pwnmaster30008d ago

Honestly if there was thing I learned from this generation is that new consoles arnt day one anymore.
I can wait 1-3 years.

DarXyde8d ago

Another important lesson from this generation: while Nintendo showed us that prices don't necessarily need to ever drop, we've now learned that waiting 1-3 years does carry some risk that prices increase. This generation is just bizarre in all the wrong ways.

LucasRuinedChildhood8d ago (Edited 8d ago )

The factors are largely external. Covid and Russia-Ukraine war causing inflation led to the first price increase in 2022.

Then we get Trump's tariffs increasing hardware prices, AI boom causing a RAM crisis, war on Iran causing a worldwide fuel crisis which impacts the cost of everything.

Gaming doesn't exist in a vacuum. The last few years have been a shitshow and lot of it was definitely avoidable.

DarXyde7d ago

LucasRuinedChildhood,

For sure. No disagreement on the external factors doing a lot of this. Where I have to gently push back however is on two fronts:

1. The pandemic definitely caused some issues: asynchronous development was a big issue and really complicated timelines and affected game quality. At the same time, when it comes to price hikes, it's really difficult to know what was genuine necessity and what was taking consumers for a ride. The pandemic brought about "stag-flation" which was increasing prices and stagnant wages, which was a problem caused by supply chain constraints. There was also "Greed-flation", where companies that were slightly affected or had no issues took advantage of the situation and squeezed everyone citing supply chain issues when there were none.

2. It's definitely true that the tariffs, AI boom, and RAM crisis were all things enabled by tech broligarchs throwing money at this caricature of a world leader, one of them being Satya Nadella. I don't think Sony and Nintendo have contributed much to this problem if at all, but Microsoft's Nadella I feel was instrumental in causing every one of those issues. Microsoft as a company contributed to both candidates (though they gave Harris 4x as much if I recall), but Nadella was all in on letting AI run wild. He paid for unregulated AI, and got a war that's not a war (even though Trump called it that at least five times on television) that screwed up helium access. So for me, I feel that one of the players in the gaming industry is a key architect of these issues, and for that reason I struggle a bit to think of it as "external".
