CPU impact - including Ryzen!
To test how the game copes with slower processors, we disabled cores or the HyperThreading functionality on the processor to simulate a Core i3, Core i5 and Core i7 from the mid-range series. The respective split of cores/threads is 2C/4T, 4C/4T and 4C/8T. We left the speed at 4,5 GHz and used the best performing GPU, namely the GeForce GTX 1080 Ti.
Project cars 2 already performs quite well on a dual-core processor, but a proper quad-core will impact performance positively, especially on lower graphics settings. On Full HD at medium settings the performance will even improve when you go beyond four cores, while the impact of HyperThreading doesn’t seem to be all that great.
|2C/4T||4C/4T||4C/8T||10C/20T||Verschil 2C/4T vs. 4C/4T||Verschil 4C/8T vs. 10C/20T|
|1920x1080 - medium||168 fps||218 fps||218 fps||245 fps||30%||12%|
|1920x1080 - ultra||119 fps||140 fps||139 fps||144 fps||18%||4%|
|2560x1440 - medium||168 fps||211 fps||207 fps||223 fps||26%||8%|
|2560x1440 - ultra||95 fps||101 fps||102 fps||110 fps||6%||8%|
|3840x2160 - medium||137 fps||140 fps||138 fps||144 fps||2%||4%|
|3840x2160 - ultra||70 fps||72 fps||73 fps||74 fps||3%||1%|
Lastly, we also tasted the game with an AMD Ryzen 7 1800X, boosted to 4 GHz on all cores. This scores lower than an Intel dual-core CPU with HyperThreading enabled. There are no scenarios where the game becomes unplayable due to CPU limitations, but when it comes to getting the highest fps, you will not find it while using a Ryzen CPU.
|2C/4T||4C/8T||10C/20T||Ryzen 7 1800X @ 4 GHz|
|1920x1080 - medium||168 fps||218 fps||245 fps||163 fps|
|1920x1080 - ultra||119 fps||139 fps||144 fps||105 fps|
