Does Hyper Thread help multitask?

[BiggieShady]

New engines like Frostbite 3 and I assume Unreal 4 are pretty good about synchronous multithreading for drawing frames.

Multithreaded rendering in dx11 works in a way that all draw calls created by say 4 threads end up in a single queue which is processed by driver's single thread. Despite that, benefits that dice and epic get from this approach is from intelligent reordering (batching) of all the draw calls in a queue so there are less state changes on the gpu when getting one draw call after another. Some of it is done by generic algorithms and some are algorithms that use data calculated offline from a given world geometry, shader collection and recorded beta gameplay data ... then applied as final optimization step.

We also can't forget Mantle and Direct3D 12 significantly reducing the CPU load for GPU tasks.

Indeed, that in combination with previously mentioned technique is going to enable so much more diversity in game objects around you.

I ran into a problem like this when using multi monitor setup. When playing a game on monitor 1 and Youtube on monitor 2, the gfx card lowered clock speeds to 2d settings. monitor your gfx card clock speeds while doing this ( just run gpu-z on second monitor to see). If this is the case you can use some gfx overclocking software to manually adjust clocks to run at 100% . When you are not running games plus Youtube just let them auto adjust.

its hardware acceleration that triggers that, i've seen the same thing.

 

[crazyeyesreaper]

Turn off hardware acceleration like Mussels said, another option is to limit BF4 to 3 cores and leaving 1 core untouched for browser / other tasks.

Sometimes I listen to youtube while playing too.

Try grooveshark.com ?

I think the problem is cpu. 100% cpu usage, no room left for the other app

Battlefield 4 2500k@4.5Ghz 100% cpu usage

 

[Schmuckley]

It could be the version of your GPU driver.

 

[mrthanhnguyen]

i did disable all hardware acceleration. gpu driver is the latest one. cpu is 100% for a long time ago. not now. I think the 2500k can't play BF4 and another app at the same time.

No game plays BF4 well. Stop wining you have the same problem as everyone that plays BF4. Same issues with BF3 and all the series before it. Its battlefield so don't expect it to be a resource friendly on any system.

If my 5 years old system (excluding graphic card) can handle it on Ultra it's not all that demanding...

Mantle?

I just ask if 3770k or 4770k can handle 2 tasks without lag, i will upgrade. I heard from 1 guy using 3770k, his 3770k at 85% usage and bf4 uses 65%. Still a little high. That wht im not sure upgrade to 3770k can solve me this problem.

no one can answer that, because we cannot replicate your system and what you're doing 100%.

 

[rtwjunkie]

I have to agree with @Mussels We cant replicate exactly your system.

Will a 3770k multitask better than a 2500k? Yes, for the most part it will, because it effectively has 8 threads.

Also, at the same speed a 3770k is roughly 10% faster than a 2600k. So hopefully you can infer the differences and determine if it is worth it.

Your current 2500K @ 4.5GHz should handle BF4 without lag.

BF4 can be temperamental and each users system has its own configuration variables. This means somebody else with a 2500K might experience no lag whilst your experience is opposite.

If you are experiencing lag with a 2500k @ 4.5GHz (which you shouldn't) then all likelihood you will experience lag with a 3770k because the performance gap is small.

Have you tried killing all non-essential start-up applications?

 

[mrthanhnguyen]

if I just playing bf4 alone. no lag at all.

 

[Toothless]

What do you have running in the background? What browser do you use?

 

[mrthanhnguyen]

chrome. and chrome running youtube on 1 monitor, bf4 on 1 monitor. lag kicks in.

 

[Toothless]

Try IE for the browser, run the videos at a slightly lower resolution, and make sure nothing else is running in the background.

 

[mrthanhnguyen]

same thing. I think the problem is the 2500k. like the video above. I didn't open youtube on second screen and cpu already 100% usage during gameplay.

 

[Toothless]

What antivirus do you use?

 

[mrthanhnguyen]

norton, and it uses like 0.1% cpu usage during gameplay

 

[Frick]

Is youtube playing flash or html5?

 

[mrthanhnguyen]

html5

 

[RejZoR]

Mantle?

Yeah. Though I've tried DX11 as well and couldn't really notice much difference. But I just kept using Manytle since it's better either way, even if by only a very small margin.
