Mid Quality Performance

Since our evaluation so far has been focused on performance with Star Swarm’s most resource intensive Extreme setting, we wanted to shake things up by trying a lower quality setting.

In this case Star Swarm’s various quality levels adjust both the CPU and GPU workload, with the Mid quality setting reducing both the number of draw calls generated and the amount of work generated per frame for the GPU. As a result we’re not adjusting just the CPU or the GPU workload, but it can give us an idea of what to expect from DirectX 12 and Star Swarm at lower settings more suitable for weaker systems.

Even with this lower quality setting, the CPU results tell us that only the GTX 980 is truly CPU bottlenecked with 2 cores. Everything else from the 290X on down can reach its GPU limit with a relatively weak CPU.

Overall the numbers are different, but the lineup is the same whether it’s Extreme quality or Mid quality. Every vendor still sees massive gains from enabling DirectX 12, though the overall gains aren’t quite as great as with Extreme quality. Meanwhile GTX 750 Ti in particular continues to see the weakest gains from DirectX 12, at only 14% for a 2 core configuration, thanks to a combination of NVIDIA’s lower CPU consumption and earlier GPU bottleneck.
