I used the GTA V built-in benchmark tests at 1080p vs 720p, and found that the benchmark results had little difference. In fact, the average fps for 1080p was higher than that of 720p. All other settings were kept the same
GTA V Benchmark Results: 1080p Frames Per Second (Higher is better) Min, Max, Avg Pass 0, 47.884686, 106.038651, 89.360901 Pass 1, 66.367462, 129.559692, 107.134224 Pass 2, 73.644211, 149.183258, 109.369591 Pass 3, 74.202469, 140.992554, 121.042595 Pass 4, 40.994385, 193.316055, 112.253723 GTA V Benchmark Results: 720p Frames Per Second (Higher is better) Min, Max, Avg Pass 0, 53.231331, 99.779015, 80.330269 Pass 1, 49.893250, 138.234314, 89.887611 Pass 2, 59.239407, 142.057755, 83.320381 Pass 3, 53.007504, 137.594223, 86.780602 Pass 4, 32.280907, 179.472031, 95.087677
I've double checked these results to make sure I didn't get the two mixed up. The 1080p fps performance in terms of minimum, maximum and average were higher than that of the 720p in almost all cases.
This is unexpected, as 1080p would be pushing 2073600 pixels, while 720p only needs to work with 864000 pixels - less than half of the pixels at 1080p.
I have not done tests in other games, but this really bewilders me. Can anyone explain it?
- CPU: Intel i7-6700, 3.4 GHz
- GPU: AMD RX 480, 8 GB VRAM
- RAM: 16 GB
- OS: Windows 10 Home, 64 bit
- GTA V DirectX 11 mode
I have the latest graphics drivers from AMD at the time of the test. Also, this is a new pre-built computer that was released late 2016 (Dell XPS 8910 SE)
