I personally think mantle is big thing for Linux. AMD+Linux+SteamOS can killed microsoft windows and nvidia if AMD focusing on this low level API.

Who needs windows if you can gaming on linux and developers can easily code closely to the metal? AMD should start focusing on mantle and catalyst driver for linux.

Acid_RuleZz Looks like not just Mantle, OpenGL extensions too... that means future games do not need 'game optimized' drivers.

As for Nvidia, their business priority seems to be cracking the mobile business. I sure do not hope them to drop desktop GPU.

On second thought, there is something going on between nvidia and valve. Steam machines are all nvidia based cards.

It is actually kinda weird when AMD introduces this new low level API and OpenGL extensions... and nvidia is mum about this. Probably, nvidia is actually ahead where valve got nvidia onboard with steamOS/linux.

I think nvidia g-sync is very important technology. We've been stuck with limitations of monitor technology. fixed refresh rate, cause frame rate to caps at 60hz. Not many have 120hz monitor.

G-sync dynamically change refresh rate to whatever gpu fps to match it. What is the point of having fast GPU but the bottleneck is your monitor? What we want is fluid motion in gaming, and refresh rate is important just like fps too.

Normally this is fixed if you turn on V-sync hmm.gif

Problem is that the G-SYNC module costs USD100 more, with that money you can buy a better monitor or higher class GPU.

The point of G-Sync is fluid motion. Better monitor still have lock refresh rate. IPS panel still stuck at 60hz, there are some can be overclock. 120hz monitor still fixed refresh rate, but minimize the tearing effect.

We pay graphic card more than USD100 to have fluid motion, not high FPS alone. Having high FPS does not really translate fluid motion in these modern day because the bottleneck is current monitor technology. Unlike old school days where 20-30 fps make big difference to give the fluid motion impression. GPU during those days still primitive and strugle to give at least 30fps at 800x600. Dynamic refresh rate is the future of gaming, and motion pictures.

I don't think it's fluid motion as opposed to removal of screen tears and v-sync related input lag hmm.gif

Nvidia demos at relatively 60fps. The benefit of g-sync is to get match fps with refresh rate. The fluid motion is when the fps is higher than 60 and the refresh rate can match it.

I would rather spent moneys more on monitor that gives the feature, rather than focusing on upgrading gpu. This is long waited technology. Everyone is busy with 3d, and 4k.. but not variable refresh rate.

Refresh rate issue is long due problem since the introduction of motion pictures.

That's not fluid motion, but rather the removal of screen tears caused by monitor already halfway displaying a picture and GPU generated a fresh new frame.

What is your fluid motion by your definitions?

The concept is good I'd say - This is indeed a long overdue issue which needed to be addressed.
What irks me are some unanswered questions though not necessary only pointing to nVidia unless stated:

1) This is an issue known for years. A solution (hardware/software) should had been implemented since years ago, why did nobody took this up much earlier? Why now when 120hz monitors had been released (admittedly, relatively young)?

2) Is nVidia going to patent and make this an nVidia-only concept? OK this is just me being paranoid, my gut's not feeling to comfortable seeing how nVidia's market recently had been diversifying (Tegra, nVidia shield), and how would they react to the recent decline in PC market share? Reminiscent of..... Apple. nVidia's making themselves unique from their competitor, which is a good thing. But with G-Sync, would they take the patent route on this attempt?
Maybe it's a good thing that nVidia implemented the G-Sync, so down the road we can see how AMD responds to it with their own implementation. Maybe AMD will reply "we will continue churning out butt-powerful cards and you just need to turn on V-Snyc". Whatever it is, hopefully nothing "closed-sourced" or strictly patented, that all.
Still, I am not gonna wait for G-Sync as my desktop is dead and I NEED a PC within this year. lol
*
Agreed. AMD should react with this. Not only AMD, but panel manufacturer more importantly. This should not be propriety, it should be industry standard. It is an issue that need to be solved.

Smoothness/fluid motion is visible even at lower 60fps with g-sync. Just like the old days gaming on crt low res with high refresh rate, even less than 60fps we can perceive the fluidness.

g-sync is still very long to go ok? whats so fun about it? looks like it u only can have g-sync if only u own a nvidia g-sync ready monitor and as usual nvidia is gonna charge very high price bcoz only they have 'it'

ok i know what can 780Ti do if it really came out, that is top the Titan oced laugh.gif

Either AMD should do something about it, or gamers will choose Nvidia over AMD. G-sync is that important. Nvidia solved problem where everybody can't solved it.

This technology should be license and standard, just like any technology breakthrough. But knowing nvidia, they won't. So, everyone should embrace this technology or else, we will still stuck at old age technology where refresh rate is fixed. No point of having 4k, 10k display if the panel is still stuck at 60hz fixed rate. Media sources (movies, tvs, games) are running at different frames and refresh rate, if panel still have fixed refresh rate, then it suck.

Dont think g-sync going to be a technology standArd.. what gsync can do radeonpro and nvidia inpector can do it for free.... but just need to know a bit of tweak
*
G-sync is a hardware underneath monitor. Not software. No such thing as tweak can make your monitor to run at variable refresh rate.

U can capped the frame to 30, 48, 50, 60, 72, 75 depends on ur monitor... and also how powerful ur card...
With this u can reduce the micro-stuter n reduce the screen tearing since the frame rate variance is minimal
For amd radeonpro.. nvidia nvidia inspector... u should play with these two great tweak apps

No bro... it is not about frames capping. It is about realtime variable refresh rate. No matter how powerful your graphic cards, the bottom line is your monitor is 60hz (unless you are using 120-144hz). What is the point with fast gpu at the end you capping it at 60fps?

When refresh rate is match with fps, it is not only solved tearing and stuttering, it gives you the smoothness, fluid motion.

The limitation is not in your GPU, it is on the display panel.

Linus opinion about Mantle and G-Sync



Discussion start at 1:27:43

Points to highlight:-
Mantle
-it's not done, performance is unknown
-frosbite engine developer not sure about mantle performance
-there should be dramatic performance improvement in BF4, if no, mantle will be a failure
-developer participation is unknown
-coding in mantle will not be the same across GCN, but there is similarities.

G-Sync
-Huge thing
-lot of people have wrong idea of G-sync and what it's actually solved
-it improves latency
-it runs fantastic at even lower fps than 60
-hardware issues; only for kepler, TN panel monitors sucks
-hoping nvidia license the tech to amd/intel, and hoping g-sync will make it into hdtv and ips panel
-gaming in 4k is horrible without g-sync


In before Linus being paid by nvidia. brows.gif

So that mean yet to be release GTX 780 Ti is not worth it because it is also based on 2 years old architecture?  hmm.gif

Haha pwned.

However, kepler architecture is early in terms of performance. AMD is lagging behind at least 9 months, GTX Titan is old, but they release it and still the fastest card at that time. The advantage is still at nvidia hands. The titan should be 680, but there is no real reason to release it when they are ahead in terms of performance with a tone down spec of GK104, and GK110 for compute graphics only.
