hello everyone, I need an opinion. for some days I have a strange stutter in the firestrike and superposition benchmarks! last week i had 441.20 drivers and i had no problem. Then to fix some bugs of RDR2 I changed the driver putting 441.34, 441.41 and 441.66 ... from there the stutter with the benchmarks began ... even putting the 441.20 drivers back often happens! My strix 2080ti is +110 on the core and +500 on the memories but it happens that the stutter also occurs in stock. What may have happened? I have never had problems, especially with superposition! Can you help me that I don't know what to do anymore?
My RIG:
I7 8700K 5ghz
Maximus XI Extreme
32 gb Ram
Strix rtx 2080ti
Nvme Samsung 970pro 512gb x2
Windows 10 Pro 1809
Msi Afterburner 4.6.1

thank you very much.
