24-Way NVIDIA/AMD GPU Benchmarks With X-Plane 11
Written by Michael Larabel in Linux Gaming on 17 January 2018. Page 3 of 3. 17 Comments

When the Intel Core i7 8700K system was running with the GeForce GTX 980 Ti, I had the Phoronix Test Suite run some additional X-Plane 11 benchmarks while recording the CPU and GPU utilization on a one second interval and running tests at 1080p and 4K with maxed out visuals.

The previous-generation GeForce GTX 980 Ti (Maxwell) graphics card didn't even get fully utilized by this flight simulator but was averaging just about 50% utilization.

And looking at the CPU usage, there were some spikes to full utilization but for the most part it doesn't look like X-Plane 11 is very well multi-threaded for taking advantage of today's modern processors.

So overall it's not the most interesting Linux GPU comparison. But at least X-Plane 11 is running nicely with all modern AMD and NVIDIA graphics cards on Linux and I didn't run into any rendering issues -- most notably the RadeonSI driver stack and even R600g working out for this flight simulator. Obviously though if wanting to enjoy X-Plane 11 with multiple monitors, be upgrade-proof for the future VR support currently in beta, etc, a more powerful graphics card may then prove handy. When the next X-Plane update is officially out I'll run some new benchmarks and see if the situation has changed.
