physics score

post #1 of 6
Thread Starter 
Hey guys,

First off, this is my current build:

Corsair Carbide Series Air 540

Intel i5-4670k

Corsair H110

Corsair Vengance pro 4GB *2

MSI Z87-G45

Samsung 840 Pro Series 128GB

Western Digital 1.0TB Blue

ZOTAC reference GTX 780

FSP Raider 650W PSU

I realized serious FPS drops during games such as Tombraider, metro 2033 and need for speed most wanted. I realized most of them were when there was smoke or physics particle. I ran 3dmark11 with and without the graphics card and realized my physic score was very low (below average). I am currently getting about 6000 for physics score on stock cpu and 6200 when I overclock to 4.3Ghz. When I check similar build scores, I see people are getting around 8500 for physics. What could be a possible reason that my phyiscs is so low? faulty cpu?

First, make sure that the physics is actually being calculated by the cpu. Physics can be done by the GPU if it is told to be. What kind of fps are you getting on the two physics benchmark tests? Is the combined test alot worse than the straight physics benchmark?

Second, make sure that the temps on your 780 are not making the 780 throttle itself. What temps is your cpu getting? i see you have an h110, but a throttled cpu could be your problem also.

Hi, thanks for your reply.

I do not know how to set where the physics can be calculated. I am getting around 17 fps for physics test on 3dmark firestrike extreme (stock cpu clocks) and 8 combined score. If I overlcock my cpu to 4.4, i get around 22 fps and 11 fps. I kept comparing with people with similar builds and I realized my 4670k is underperforming than most 4670 (non-k)s.

780 tems are perfectly fine. I am always keeping an eye on it during benchmarks with riva tuner. Temps dont go over 62 C. I don't understand what throttled cpu means. How do I fix this?

Throttle means that if your CPU or gpu get too hot, your computer will down clock those components to ensure that your components do not fry. Your temps are fine though, I don't think that your CPU or gpu are throttling.

You can set the physics affinity in the nvidia control panel that came with your graphics driver. If it is set to auto, it will automatically assign physics to the best component to run it, in your case, it should be your CPU.

Speaking of drivers, make sure yours are up to date. Go to nvidia.com and click on drivers to download the latest ones.

damn... I always install latest drivers via Geforce experience. If you are talking about PhysX from nvidia panel, I did switch them and benchmarked both but there was no significant difference. Cant find out what is wrong..

Have you tried any other CPU benchmarks to see how your CPU compares to others there? That would tell you if you have a bad CPU
