I benchmarked my machine before and after the Win10 April Update.
I want to stress this is a single benchmark on a single computer. The benchmark I ran was PCMark10.
I would appreciate any benchmark results anyone can share.

***2 MAJOR UPDATES TO THIS ARTICLE
see the end of this post…
My rig:
CPU: Intel i7-8700k
Mobo: Gigabyte Z370 AORUS Gaming 7
GPU: Zotac GeForce GTX 1060 AMP! Edition (Nvidia)
Ram: 32GB
Drives: x2 Samsung 960 EVO NVMe M.2
OS: Win10 Pro
Here are my last 5 benchmarks.
The highest benchmark after the April update was 5315 vs. 6057 before the update.
5315 is 87.75% of 6057
6057 is 113.75% of 5315
Not good.
(I am aware that the GPU clock listed is different. I didn’t adjust anything.)
The area that most felt the effects was Digital Content Creation. Crazy.
(And yes, same drivers)
My score before the Meltdown and Spectre Windows and BIOS Updates was 6392.
5315 is 83,15% of 6392
6392 is 120.26% of 5315
***UPDATE May 2, 2018, 11:15(EDT)
This whole thing has bothered me immensely. Racking my brain, looking at results past and present.
Samsung released new NVMe drivers and I tried those, no luck. In desperation I broke down and tried Microsoft’s bullsquat Ultimate Power Plan and Game mode which, as I expected, resulted in absolutely no changes. I even tried overclocking to 5Ghz. Even that doesn’t bring my score back up.
Nobody else is seeing what I am. Frustrated I am staring at all the benchmark results. I’ve restored from images half a dozen times in the last few months. Did I miss a change somewhere? I start combing through my installed drivers… Well, this is embarrassing. My previous Win10 benchmarks were using Nividia 390.65 drivers and I’m now using the 391.35 drivers. Could it be?
I clean install the old 390.65 drivers and run PCMark10 again…
Holy crap! It was the Nvidia drivers all along?!
So with new NVMe drivers and old Nvdia drivers I’m now back to my post Meltdown & Spectre patches scores.
***UPDATE #2 May 2, 2018, 13:57(EDT)
OK, try to follow along.
Nvidia Drivers:
– Before I stalled the April Update I was running 391.31. After update PCMark10 score 5315.
– Then I installed 390.65 Nvidia drivers. PCMark10 score 6139.
– Then I clean reinstalled 391.31. PCMark10 score 6024.
– The I clean installed the newest drivers, 397.31. PCMark10 score 6059.
I am left with the conclusion that the Win10 April Update did something to or mis-intalled the drivers.
-END-
(for now)
That is a big delta, my guess something changed like maybe drivers, some old settings got reverted to default or something.
I don’t have PCmark10 installed so have no baseline, but I did test Cinebench15 and CPU-z BM, both show same results as before.
Not sure what it is. Got similar results running insider. Thought it was an anomaly. It wasn’t. I’m gonna try other benchmarks tomorrow. Thinkng it is NVMe and/or GPU related.
That sounds more like a meltdown/Spectre slowdown, I hear NVMe suffer more than SATA.
Also just did Geekbench 4 before got 4593 single core and 13685 multi, that on 3570k@4.5ghz.
After 4605 single core and 13927 multi, that on 3570k@4.5ghz
I updated my BIOS just before clean installing 1803 and I have to say that I am very satisfied with the performance.

Features removed or planned for replacement starting with Windows 10, version 1803

Thanks. Will get that posted with the news today.
On Pcmark 10 i get between 5662-5697. My MB hasn’t had a bios update to date. But I do have all windows 10 updates installed. No prior baseline to compare to. BTW I and running a 4790K on a Maximus VII Hero overclocked to 4.6GHz
After installing beta bios for my Z97 board and re-running PCMARK 10 I came up with 5774 a little bit better than before. I’ll run it a few more times. BTW I am not disabling and background app or services.
Glad you got it sorted, that is kind of weird GPU driver would do that much on PCmark, you think more on a graphic BM like Firestrike.
I would install newer Nvidia drivers 397.31 or wait for next which should be soon.
On the “Ultimate power plan” did you look at reg and see what they added?
Looks like it is only HD set to no sleep, there only 2 keys to it.
Maybe it is unfinished or you really do need a Pro workstation version, as I used the hack to copy the hidden one.
It isn’t the actual driver. I did 2 attempts at installing the April Update on this rig. Both attempts said the previous driver was installed. Both attempts left me with those low scores. In both cases reinstalling ANY Nvidia driver solved the problem. The only reason I can see is that Windows did not correctly reinstall the driver. So, IMHO it is Microsoft’s fault.
As for the “Ultimate Power Plan”. It’s snake oil. No advantage over the Hi Perf plan. I checked using JV16, no registry changes.
Hi, i’m looking for information about the performance issue regarding the april update, and i’m here ! 🙂
For me and my friend, we have a BIG performance issue on realbench with this update.
I run a 7700k @ 4.8ghz with 16Go RAM and a ssd 850 EVO and gtx 1070, here are my results :
Before the update, on 1709 my results are : (on realbench 2.56)
Image Editing: 115140
Encoding: 86504
OpenCL: 95940
Heavy Multitasking: 98615
And after the update, now on 1803 :
Image Editing: 113003
Encoding: 58646
OpenCL: 96473
Heavy Multitasking: 67017
As you can see, everything is almost the same, but the “Encoding” part is reaaaally bad now !
I tried to clean install again my nvidia driver but this is still the same. (anyway i always do a clean install)
My friend did a windows rollback to 1709 and now his results are back to normal. So the problem is this update.
Anyone can confirm the same problem ? Any solution, even if i think there’s no solution 🙁
Thanks.
Regards.
Yes. I believe 1803 carries performance hits depending on hardware. NVMe drives are hit. Meltdown & Spectre updates are an issue. The “fix” is to use 1709 and/or do not use Meltdown & Spectre bios / firmware updates.
You can also try the latest Nvidia drivers. OR, I went back to 390.65 drivers and it helped: https://www.tweakhound.com/2018/05/08/windows-10-game-mode-and-ultimate-performance-power-plan/
Thanks for your answer.
I will try the old driver to see if there is a change.
But the bios update is not really a problem, because my friend is now in 1709 but with the last bios updated for Meltdown & Spectre and he still have the same good results as before (on a MSI Z270 gaming 5). The main problem is really the windows update.
I will go to see your link 🙂
