Let me start by saying that I have not created this information. This information was shared by an EVGA user that closely monitors his hardware, and he noticed an anomaly with driver changes that is very easily reproduced just by switching drivers.
Lets start with his information that was initially posted:
The Geforce Game Ready Drivers 4xx.xx Drivers on the GTX 10 Series Drop more than 2/3 in CUDA Performance from the 3xx.xx Drivers
PG AP Runtimes running on the EVGA GTX 1080 Ti SC Black Edition Graphics Card. Smaller Numbers are Faster or Better.
Driver: 411.70 Run time (sec) 2,619.05 CPU time (sec) 45.12
Driver: 416.16 Run time (sec) 2,356.02 CPU time (sec) 43.10
Driver: 416.81 Run time (sec) 2,507.31 CPU time (sec) 44.83
Driver: 416.69 Run time (sec) 2,609.08 CPU time (sec) 46.11
Driver: 391.35 Run time (sec) 851.45 CPU time (sec) 40.19
Driver: 390.65 Run time (sec) 852.15 CPU time (sec) 38.39
First question I asked, “where is this information coming from?” This is from BCavanaugh’s PrimeGrid tracking. The above number relate to tasks completed by prime grid utilizing CUDA. As you can see above, from 411.70 and forward, the times are extremely high compared to the 391.35 and lower drivers.
We are not trying to point fingers or blame NVidia for anything here, but we would all like to know what is causing the massive slow down on the 1080ti Cards when using the 410+ series drivers.
BCavanaugh has done extensive testing, and changing drivers. reverting back to the 300 series drivers yield large improvements for the programming.
I am not sure if I am allowed to post Links currently. I will try, and if it gets removed, I will transcribe what I am able to.
http://www.primegrid.com/results.php?hostid=502676&offset=260&show_names=0&state=4&appid=11 <- Overall results currently running the latest driver, these will update as work units are completed. If the 300 series drivers need to be loaded to show testing, please let me know and I will try to talk to the original owner of the information, BCavanaugh, and get the 300 series drivers running for new results.
http://www.primegrid.com/workunit.php?wuid=587652125 <- 300 series driver directly compared to 400 series drivers.
http://www.primegrid.com/workunit.php?wuid=587803428 <- 300 series drivers only
I am not a boinc user. I am not a prime grid user. I am simply transcribing as much info as I can, just in case someone else can test this information and we can get NVidia to take a look into this and get it corrected.

Please let me know if you have any questions, and I will try to ask BCav and pass on any information.
