Hmm, downloaded the BF4 patch, but the battle log link to the latest beta drivers only shows 13.11, not 14.1. :C
 
I'm just going by what I personally have done, and AMD's screenshots.

Anyway, I re-tested that area and sure enough, AMD had taken screenshots during grenade explosions, which explains the red hue and all that.

And yes, there was a frame rate drop, although not drastic depending on how close it was. If it was a direct hit, the frame rate would drop into the 80s.

If it was close but not direct, then frame rate would stay above 100 FPS, but below 110 FPS.

Judging by AMD's screenshots, I can tell the grenade explosions weren't direct hits because there are no injury indications on screen ie blood splatter.

They were obviously using god mode for the demo. Wouldn't do to die every 2 seconds trying to show off the game.
 
And what did Microsoft contribute to DirectX? Only the include header files and docs?

Direct3D definitely has it's inefficiencies, but NVidia has seemingly managed to work around it fairly well, while AMD hasn't.

Take DX11 multithreading for example. NVidia has this feature enabled in it's drivers, and it has resulted in very large performance gains in games that use it; best example being Civ 5.

AMD on the other hand doesn't have it enabled after how many years now, and by all reports, tried to implement it but could not get it to work properly. It either gave them no performance benefit, or worse, a performance decrease.

Look at recent benchmarks of Civ 5. AMD isn't as far behind as to call it a very large performance gain anymore.

Is this the mantle thread ... oh that grasping the multithreading straw stuff again? 😕

So, the driver is coming tomorrow. I guess it doesn't matter that BF4 updated today without the driver due until tomorrow.
 
OK I did some checking, and you are right. I think that particular scene had a workload that used 4 cores, so that would put it around 3.5 to 3.7ghz..

But even then. They stated it was at 3.5ghz. Since it's overclocked, I'm sure it would be safe to make an assumption that all 6 cores ran at 3.5 and stayed that speed.
 
Look at recent benchmarks of Civ 5. AMD isn't as far behind as to call it a very large performance gain anymore.

This is the last Civ 5 benchmark on Anandtech, from the GTX 770 review. They retired this benchmark apparently as it's not in the 290/290x review:

GTX 780 is almost 50% faster than the 7970GHz , despite being only 20% faster on average.

This only helps in CPU limited situations remember, which explains why the GTX 780 has such a huge lead, as it's the most CPU limited card in that group.
 
You're doing it wrong. You're comparing your OCed CPU dealing with frames at a rate of 9.30 ms (107 FPS) with a stock CPU dealing with frames at a rate of 13.24 ms (75 FPS).

Honestly, I'm probably going to run my CPU at stock clocks and see what kind of performance I get..

That's the only way I'll know for sure..
 
Are your prices in line with the US before the "mining tax"? Also I seem to remember that some of the world doesn't have real access to computer hardware in their home country no? Like some people have to order from elsewhere? Probably a small percentage.

I am not really familiar with how supply and pricing is in Europe for example.

Well, they aren't in line cause I live in a 3rd world country, but as a comparison.

http://nanodog.net/components/display-cards/gigabyte-geforce-gtx780-ti-oc-edition-3gb-ddr5.html

So that is U$815 for a GTX780
U$993 for GTX780 Ti
U$721 for R9 290

But they are as they should be. 290 cheaper than 780.

I feel bad for you. That is so incredibly over priced. You're better off buying one on eBay and paying the shipping. =(
 
Could that be caused by AFR, so that each frame takes longer, but drawing them in CF doubles fps?

That makes even less sense. If anything in your system is taking 14.02 ms to deliver a frame you can't have 116 FPS unless they're doing some space-time folding.

Yeah, you're right. The FPS figure is doubled with AFR.

I don't know everything about TrueAudio, but if this tech help to reduce CPU bottlenecks on games will be all good to PC gaming scene.


The efforts by GPU makers to reduce CPU needs on modern games(NvApi, Mantle, Arm/Cpu cores on GPU die, TrueAudio) is somewhat the biggest revoltion on PC gaming since the 3D accelerators.


This approach will make GPUs more and more suitable to CPUs with SFF forms level of performance. Is the biggest strike PC Gaming has ever did against consoles, and only need developers help to become successful.



For ones that didn't understand my last statement, imagine the situation: With the system performance needed to pair high end cards halved, more gamers with low-end systems can have high end graphics.
With costs of gaming PCs halved, the PC becomes more attractive to console gamers.
 
Who in the world would pair those? So basically Mantle wasn't made for enthusiasts, yet it was beat to death on this enthusiast board.


For those of you with beefy CPUs where the GPU is the limiting factor, AMD says don't get your hopes up. It writes, "An API change is unlikely to make a drastic change in these scenarios, as GPU resources are being maximally utilized in a fashion that is difficult to improve at the API-level."

No thank you.

58% improvement with crossfire???? WOW!!!!! Why arent more people excited about this? I really cant wait to get a second 290X and a 120HZ monitor now
 
This is great especially for the future, we haven't been getting much more CPU power lately, where as we still do get a good bit more GPU power each generation, along with the ability to use multiple GPU's.
 
Download the star swarm rts engine demo on steam guys!

I am running on dx now. That is some serious rts engine we have there. A lot of stuff going on. Thats some change for the rts games comming for sure on dx as well. Some serious multicore coding for sure! What a blast of a tower defence game this engine could make.
Now we just need the mantle drivers - yeaaa

What kind of performance are you seeing?

And still, the confirmed games using it can be counted on one hand. It was even patched away in Far Cry 3.
And today. repi stated it was "fundamentally broken".

But since all developers and Nvidia apparently need to do is use DX11 multithreaded rendering, you just have to relax and let AMD users have their moment
