    I wasn't sure where to put this thread, however yesterday I upgraded from windows 10 build 1809 to windows 10 build 1903 on my main rig, and after doing som testing with 3Dmark Time Spy and other benchmarks I found myself with lower GPU performance than usual ?. [​IMG]

    I checked my OC settings on the cards (RTX 2080Ti NVlink SLI) and they were just fine and what they have been set at for months now. I then updated from Forceware 430.86 to the latest Forceware 436.48 but that didn't help at all.

    Usually I would get around 22'200 in Time Spy standard total score, the GPU score around 26'700 and CPU score around 11'300.
    However now I get around 21'500, the GPU score is around 25'900 now, so around 800 points lower, and the CPU score is still around 11'300.

    The total score in Time Spy Extreme however only differs between 11'100 and 11'050, so here it doesn't seem to loose any significant GPU performance (both around 13'900 GPU score).

    Testing CPU performance with CPU-Z and Cinebench R15 and R20, showed pretty much the same results, seemingly unaffected by the update.

    I've tested in AC Odyssey, Far Cry New Dawn, COD WW2, BF5, Control, Wolfenstein Youngblood, Anno 1800 and 4 of the games show about 3~5FPS loss while the others remain untouched.
    Have some of you experience the same behavior in performance loss ?.[​IMG][​IMG]

    I will admit that the update to 1903 wasn't without issues. I realized that the new update yet again bricked any overclock settings on the X99 platform with a Broadwell-E CPU, so insted og 4.2GHz my CPU was running 3.5GHz[​IMG]. However "luckily" I found out MSI had released a Beta BIOS to the X99 platform to yet again update the microcode, so overclocking was possible. So naturally I flashed to the new Beta BIOS and I got my 4.2GHz back again.[​IMG]

    I am really wondering if all these Intel security patches and fixes to both the OS and the BIOS, are starting to hurt the overall combined performance of my system.

    My wife's PC with X99 and a Haswell-E i7 5960X had no issues running build 1903 (just like the previous ones, no Intel bug or microcode update needed on those cpu's) and even her 2x RTX 2080 NVlink SLi cards with and outdated forceware 417 driver experienced a 200point performance boost in 3Dmark Time Spy going from a total of 18'200 to 18'400points.

    I am a confused man....[​IMG]
