Hello everybody

I have a weird GPU load when gaming. It's hard to explain so I attached an image. The GPU load goes from good (which is around 60 FPS) to bad (around 25 FPS) and back to good. This of course results in stuttering which is really annoying. When I lower the settings the spikes remain but the max and min load are just lower...

I have tried multiple driver updates from AMD, just did a clean install of Windwos 7 but nothing changes.

My gear : Windows 7 Professional 64bit / ASRock 960GM/U3S3 / AMD FX-8150 until recently OC to 4.2 GHz, no OC to 4.5 GHz / Radeon HD 7750 2GB / CORSAIR CX750M / Cooler Master Hyper 212 EVO / Western Digital WD Green WD10EADS 1TB 32MB (OS) / Western Digital Caviar Green WD10EACS 1TB 16MB (Storage).

This surely can't be normal... Any ideas?

Thanks! Tom

More about : gpu load fps dropping spikes

August 3, 2014 6:32:20 AM

HD 7750 is a low end card.
What games do you play.
In some games there are some points where draw distance is too much for the card to handle so GPU load increases.
For example if in GTA 4 you are in a building you will have Less gpu load and high fps but in the open world your GPU will be Rendering textures and displaying a large world with small details the GPU load will increase Thus decreasing FPS.

If fps is dropping and going up even if you are still that may be a problem but tell me the games.

Hello Usman Sajid

the games I play are Wolfenstein The New Order, Watch Dogs, Sniper Elite 3, GRID Autosport, F1 2013, Assassin's Creed IV Black Flag, Thief, Call Of Duty Ghosts.

Is the 7750 that bad then? I know it only has 800 MHz core and memory clock, but the 2GB storage can be handy (in the game Wolfenstein The New Order). Should a little OC help?

Isn't it weird that the spikes remain even at low settings?

Nope HD 7750 is that bad especially in watch dogs wolfenstien black blag.

You should also see that in Sniper Elite 3 , Ghost you will have less stutters

Wauw, I didn't know it was that bad at 800MHz... There are multiple threads online of people with this card playing highest or medium settings (eg https://www.youtube.com/user/GPUTestingTeam/search?quer...). Shame I cant play these fine games at highest or even medium settings.

Would a SAPPHIRE Radeon R7 250X 1GB do the trick? But can my mobo support the DDR5? If not, which graphics card under 100 EUR would you advise?

Yes GTX 750 ti will do it.
I currently have GTX 750 ti with a core i5 plays Watch Ultra 720p and High on 1080p.
It is a great Overclocker. Try to get an MSI which stays cool.

Hello all

any suggestions closer to 100 EUR? What about sort of the same card but in the DDR5 version? Will a DDR5 work on my motherboard?

Shame this card doesn't work, there are plenty of other people where it does te job : https://www.google.be/webhp?sourceid=chrome-instant&ion....

Hello

sorry for the fast double post, but could there be another problem?

I just did what Usman Sajid asked (If fps is dropping and going up even if you are still that may be a problem but tell me the games) and in Grid Autosport, I stood still for an entire lap. There were no moving things except for a little smoke.

The spikes went up and down again, the whole pattern in the GPU load remained, even when the other cars crashed into me after one lap (then there should have been a rising GPU load) : https://imageshack.com/i/ezuNBSXqg.

Any suggestions please?

Can be another problem, Try contacting AMD as it maybe drivers issue? Has spiking started recently? Or form the start.
Get a RMA and if still it stays then its probably weak card.
Are you running at 1080p?
1gb VGA mem is also a problem in new games

Hello

I now have this graphics card for one and a half year. I can't remember how it was in the beginning but it was already spiking last year. I have already tried the following previous driver versions 12.10 and 13.12, but the problem remains.

I'm running in resolution 1280x1024.

I also noticed that the spikes are moving simultaneously with the core voltage/core speed/multiplier. Whether Grid Autosport is fully running (racing) of not (paused), the spikes remain. When the GPU load is low (50% load), the core voltage is at 0.8V, the core speed at 1400 MHz and multiplier at 7. When the GPU load is high (85% load), the core voltage is at 1.5V, the core speed at 4600 MHz and multiplier at 23.

Any suggestions would be really welcome.

Do you mean don't OC mu CPU? In that case I had the problem that my CPU was bottlenecking my GPU...
My GPU isn't OC.

Well your graphics card is not that strong to bottleneck your CPU.

Anyways FPS spikes are because of your slow graphics card.
Get at least a gtx 750 ti or if you want to go higher get R9 270/X

Hello Usman Sajid

I was looking to order the MSI GTX 750 TI but would an Asus r7 260x 2gb gddr5 do the trick for playing the above games in High settings? Price wise it's the same, but it looks like the r7 260x 2gb gddr5 has a little more clock speed (1188 MHz) and a lot more memory clock (7000 MHz)? I'm not really worried about the power difference :-).

Thanks for your replies! Tom

Clock could be increased like my gtx 750 ti is 1200Mhz.
GPU is the main thing.
GTX 750 ti is 15% faster in gmaes and uses as much power as hd 7750.

You can't really compare gpu's by looking at core speed or memory mhz. You need to actually look at fps comparisons.


Also people lie about their rigs, especially on youtube.


A r7 260x trades blows with the gtx 750 ti depending on game.

Check MSI oced 750 ti vs r7 260x
Its from all types of games and benchmarks which gives an average of real world performnace

Reference 750 ti = 44.85
Reference 260x = 41.35



Now, you are comparing an overclocked model to a stock one.
You should be laughing at yourself, as the 260x's can also overclock quite nicely.

Like I said they trade blows.

You should look at a 7870/265 they can be had for around the same price if you look.

Hello

so I bought an Asus R7 260x. First impression is that the spikes in some sort remain.

I cannot get a stable GPU load and can feel it in the three games I have already tested (Wolfenstein The New Order / GRID Autosport / F1 2013).
Updated again to the latest driver, incl beta.
Tried without my CPU OC (so Bios to stock).

Any suggestions anybody?

Hmm maybe check your card on a different power supply ,
I think power supply cant keep up the wattages and gpu load goes high when it gets enough and low when its out

Hello, what do you mean with a different power supply? There is only one cable that can be connected to the card and then connected to the power supply. The voltage of the graphics card seems stable.

When i run performance test, the gpu load is really stable as it can get, around 100% all the time.
Meanwhile i have disabled the cool and quiet function and my cpu multiplier and voltage is also stable now. Another possible cause solved.
But when gaming, the gpu load goes nice and high as expected,for high settings, but every few seconds drops to 0%.

Right now i am trying different driver versions, but without luck so far.

Not cable change your power supply , there may not be giving constant wattages to card.

Hey, my previous card didn't have a power supply, just the pci-e slot. So the cable I had plugged in the graphics card was new. But I followed your advice and changed the cable (luckily I had two pci-e cables that came with Corsair CX750M), but nothing changed after the restart.

How come the GPU load is stable when testing, but when gaming it's dropping to 0?

Has anyone mentioned that this might very well be an issue of dried out TIM or anything heat related? I would instantly suspect that it's a simple heat issue you are having either in the CPU or GPU side. Monitor fps spikes with heat spikes you may be facing throttling.

Hello

so I have changed the power supply (misread that post so I thought it was only the cable) to my previous model, but no result there...

What is dried out TIM? The CPU is running at 43 degrees celcius. The GPU has 45 degrees celcius.
How can I monitor the heat spikes?

I installed MSI afterburner to check the FPS. Max was 47, min 0. Mostly they go from 25-30 to 0.

I dont believe your issue is with the graphics card at all. Its clear from the first post that the FPS drops are due to the GPU load goin right down, this is usually to do with a bottleneck elsewhere, stopping you from getting the full capability of your GPU.

I suspect the problem is your motherboard. The FX 8 Core CPUs draw a lot of power and many lower end motherboards cannot cope when the draw is high, like in games. The VRMs on your board have no heatsinks or cooling, this can cause VRM throttling.

http://www.overclock.net/t/1314862/vrm-advice-for-amd-m...


I would try and get some sort of heatsink(s) and some thermal tape to cool the VRMs on your motherboard (The line of 4 black modules behind the I/O panel, next to the CPU socket) and also make sure the airflow in your case is up to scratch (do you have intake/exhaust fans?).
