Dear Redaktion!
I have the same model (except mine has single channel 16 gigs of ram), and I have way less fps in games than you do. For example, the dota 2 benchmark with the timedemo gets me an average of 79 fps with the highest preset, the GTA V pass 4 with the ultra preset used by you gives me an average of 54 fps, and I experience serious drops in Battlefield 5 too, in the mid 40-s, just while running around in multiplayer.
In the case of GTA 5 i have a GPU usage of 50-60% at max, and the MSI afterburner indicates a power limit, while the card is sitting between a GPU clock speed of 1750 -1850 MHz (which is strange since the boost clock should be 1440 with this card). On the other hand, the 3Dmark firestrike (1920x1080) benchmark gave me 19506 points for the graphics score, which is a bit higher than yours.
Do you have any idea why my model performs way worse than yours in games? Everything is set to high/maximum performance in windows system settings, and in the nvidia contol panel.
Thanks in advance,
