Low FPS with little CPU/GPU utilization

[martyj]

My game has really low frame rates. Between 14 and 24 fps.

I profiled my game today and the GPU utilization and CPU utilization are super small.

This makes me think the bottlekneck is either memory bandwidth or PCI Express bus restrictions.

Any ideas on how I can resolve these performance problems?

 

Thanks,

Do you have these problems with oher Software or games

[martyj]

@M0ID No. It's just with my game.

Here is Joshs optimization guide.

@Thirsty Panther

I've gone over that post often.

The problems I am experiencing do not seem to match any of the issues listed.

What hardware are you useing?

And are you running debug mode? Cuse that slows down a little...

[GorzenDev]

if you are using vs2017 and have heap profiling enabled it will drop your fps significant

[martyj]

My hardware:
CPU: AMD Ryzen 7 1700X

GPU: Nvidia 980 TI.

I modified by build process to optimize the build for speed and removed debugging information, and this doubles the FPS to 30-45. But considering my GPU I would expect a much higher FPS. My screen resolution is 95% of 1080p.

Dropping my resolution doesn't help with framerate as well.

Polygon count: 500k

Shadow polygon count: 420k

Batches: 520

Ok, your hardware pretty lit.

so your running a big map? Or do you have a model with extreme polycount... 

Are you running fine on a blank map?

I dont know much about the engine btw

[M0lD]

Is there a cap in the engine that says how much it can take on the Cpu? Else from cores
