Do you even bottleneck?

Is a CPU bottlenecking the GPU's performance when the CPU runs at 100% when playing a game?

hi... ..how much is ur gpu running at...??

I honestly don't even know. I don't think it can be checked with GpuZ/EVGA Precision/HWmonitor Utility.

[Manny Calavera]

not really, if the gpu has decent load.

 

but if cpu has 100% and gpu like 50%, then its bottleneck

it can be checked by gpuz..under sensors tab..there will be the percentage utilization..check for max...

Well I've certainly had experience with this (G3220 with a 280X ) and the CPU was always at 100% load when gaming. I saw a minimal drop in fps but a metric but ton of stuttering when I switched from my 4670K. What are you using atm?

It is when your CPU cant read and write to the PCI-e bus fast enough for your GPU to do its optimal ammount of work.

And how to determine if it does?

I'm pretty sure there would be no bottleneck, keep in mind that if your playing a game the CPU and GPU will work as hard as they can. You'd be able to change the max CPU performance somewhere, therefore alleviating the 100% CPU usage.

as i said before, by looking at gpu load

 

if a cpu is bottleneck, the gpu wont do as  much as it could since cpu is bottlenecking the "pipeline"

[nokturrduk84]

Yes, it's bottlenecking your 660. My old cpu was also always 100% when I played games, and I felt terrible lag if on servers were entering many other players.

You need Intel CPU, something like i5 & you'll be fine. Even i3 can be good with 660.

oc the chip and you should be fine for most games.

even if there are bottlenecks its not life changing

I can't be arsed to get an aftermarket cooler ( 212 evo ) lol. I'll keep it at stock.

You're using the Phenom stock cooler?!? My god you're brave to bear that noise.

This stockc cooler intakes cold air and spreads it weirdly out of the sink ( vice versa to a normal cooler ) it's weird but cba to upgrade.

Crappy fan focus then. I'd still upgrade because it makes your computer so much happier.

Probably, but within the next year I'll throw away the case, motherboard, CPU, CPU cooler and the RAM lol.

Can I have?

A really shitty OEM case and motherboard ( worth literally nothing ) and the CPU is burned like hell

People are missleading you here.

 

Wile sometimes true, it isn't always the case that your cpu is bottlenecking your gpu when cpu is 100% and gpu around 50%. Some game engines, usually used in mmorpg's use cpu alot more then gpu. Wile the cpu would be 100% and gpu 50% doesn't mean there is a real bottleneck.

Mostly Battlefield 4 though where it is at 100%.

I usually play Tera maxed out, wich takes my 4670k (4.4) to 100% wile my 280x is around 35-50% load. But i'm kinda sure there isn't a bottleneck. Even if there was, im around 80fps most of the time, so i ain't even mad.

Is a CPU bottlenecking the GPU's performance when the CPU runs at 100% when playing a game?

No. When your gpu is below 99% that's a cpu bottleneck.

SLI doesnt work there thats why you don't see any load on the 2nd gpu or 1st whatever. Basically when the gpu loads are like at 10% I was getting a freaking huge cpu bottleneck but once it reached 99% the workload was much less intensive on the cpu and therefore it was fast enough to feed a gpu and the result is massive.

You could have your cpu at 100% and your gpu at 99% but thats extremely extremely rare.

If I can list a few games where you'd be CPU limited with a 3930K@4.5GHz orsomething and two 780's; BF3/Borderlands 2/Elder scrolls online or just literally ANY mmo/rpg, BC2, BF4, PS2, Dayz/Arma etc. Mostly heavy multiplayer games are always cpu bound.
