Influence of CPU
In order to test how the game handles slower processors we turned off a certain amount of cores of the processor and/or HyperThreading in order to simulate a ‘Core i3’, ‘Core i5’ and ‘Core i7’ from the mid-range series. The divide of cores and threads is respectively 2C/4T, 4C/4T and 4C/8T. The clock speed did stay the same at 4 GHz. These tests were all performed using the fastest GPU available, namely the Nvidia GeForce GTX 1080 Ti.
Racing games are usually not very CPU-intensive and a quad core only shows its value at Full HD and WQHD with medium settings. At more demanding settings, namely WQHD and 4K ultra we see that a CPU with more than four cores has an added value. However, the differences are relatively small.
|framerate in fps||2C/4T||4C/4T||4C/8T||8C/16T||'i3' vs 'i5'||'i5' vs 'i7'||4C vs 8C|
|Full HD medium||252||288,3||282,2||290,7||14%||-2%||3%|
|Full HD ultra||146,9||145,8||139,6||139||-1%||-4%||0%|
|Ultra HD medium||164,2||164,8||166,9||167,7||0%||1%||0%|
|Ultra HD ultra||65,5||65,1||64,2||67,2||-1%||-1%||5%|
In the frametimes we see a small gain of the quadcore in comparison with the dualcore at Full HD and WQHD medium, but the 8-core does not offer extra performance here.
