I tested my laptop using the ultra high settings. Laptop: HP Pavilion Gaming 15-ec1026la, upgraded with a 8GB stick for dual channel. CPU = Ryzen 5 4600H RAM = 16GB DDR4 (8x2) @ 3200MHz CL22 GPU = GTX 1650 4GB
And my results were: Average FPS = 20.7 (25% higher) Minimum FPS = 14.8 (23% higher) Maximum FPS = 25.8 (no reference) Low 0.1% FPS = 15.6 (25% higher) Low 1% FPS = 17.8 (36% higher)
I think the results can be explained for the different CPU, because all other specs were practically the same. Also, for High and Medium settings my average results are High: 35.7 FPS (0.6% higher) Medium: 50.1 FPS (5% higher).
