When testing the ASRock A75 Pro4 in Total War: Shogun 2 with Microsoft DirectX 9, the performance differences between the ASRock A75 Pro4 and the MSI A75MA-G55 were minimal at best. At 1280×1024 the ASRock A75 Pro4 averaged 52.94 frames per second while the MSI A75MA-G55 averaged 52.63 frames per second. Increasing the resolution to 1920×1080 the ASRock A75 Pro4 averaged 35.64 frames per second and the MSI A75MA-G55 averaged 35.5 frames per second.
In Batman Arkham Asylum the results seem a little bass ackwards. Of our three AMD socket FM1 APU motherboards the ASRock A75 Pro4 had the slowest performance at 1280×1024 with an average of 50 frames per second compared to the 51 frames per second of the other boards. Cranking the resolution up to 1920×1080 the ASRock A75 Pro4 averaged 34 frames per second which is the fastest of the three APU systems.
