GPU % usage

Recommended Posts

Just curious what others are seeing. Running a 3770 @4.7 with GTX780. Was using MSI Afterburner to check temps and noticed that my GPU % rarely got over 40%. I also used Kombustor to bench the card and it ran along at 99% with no issue so I know the card is ok.

 

I was under the impression that P3D2.2 put some good loads on the GPU - 40% isn't even breaking a sweat.

 

Am I misunderstanding something?

Do you have tessellation set to 100%?

Yes.  Most other sliders are at max except for water. And using 1024 textures. Maybe I'll try some heavy cloud cover and see if that kicks it up.

Be happy with the mid range load at your GPU. But you can change some settings with nVidia Inspector and you may easily reach 99%.

The GPU load varies massively with settings and the situation. Some things mainly affect CPU load, others GPU.

 

These tend to have the most CPU impact:

- The aircraft. Complex aircraft often require more CPU, but not necessarily: some are better optimized than others.

- AI traffic.

- Road traffic.

- Autogen (although better in 2.2).

 

These mainly affect the GPU:

- Shadows.

- Weather (amount of clouds/fog).

- Water quality.

- Anti-aliasing, esp if you enable SGSS in NI and it's cloudy.

 

If you're CPU-bound, your GPU will be less than 100% and vice versa. Over Manhattan on a sunny day in a complex plane with traffic, my GPU will be only 40% or so (despite being only a GTX760), because the massive CPU load is limiting my frames. Conversely, flying over open fields in overcast weather my CPU will be only 50% and my GPU 100%.

Thanx Loge - that makes sense. I'm happy my card isn't stressed but I was just curious
