Windows 10: Virtualization and gaming very slow on 1809

Hi,

I recently re-installed Windows on my laptop to get 1809 before Windows Update got it.

Everything is quite fast as before, but Linux Virtualbox VMs and all big games (GTAV, The Witcher 3, Far Cry 3) have unacceptable lag that makes them near unusable. VMs have a roughly one-second delay reacting to mouse input, and games have less than 10 FPS; in some situations they are so slow that I can't play at all. On 1803, I usually had near-instant reaction in VMs and between 30 and 60FPS in these games, with only thermal throttling coming up sometimes.

I have all the latest Windows updates, I tried with the Windows Update-supplied Nvidia drivers, then with those from GeForce Experience. Dell's SupportAssist fails to install the latest Intel Graphics drivers, but since Windows Update doesn't have these I suppose I have the version I'm supposed to have.

I have no idea in which direction to search so I don't know what information may be useful, hopefully someone will have an idea and ask if necessary.

:)

 

Slow download speed after creating Hyper-V External Virtual Switch


Hello.
After buying a new PC (its specs are on my profile), enabling Hyper-V and creating a new External Virtual Switch, I notice that the download speed drops dramatically. My internet conneciton is 1Gbps down and 200Mbps up.

Without External Virtual Switch:

• Speedtest (I get 944 Mbps download, and 214 Mbps upload) --> Speedtest.net by Ookla - My Results
• CPU usage while on Speedtest (no core is maxed out):

• Iperf with a host on the same LAN (upload 911Mbps, download 777Mbps):

• Lan Speed test (746 Mbps upload and 716 Mbps download):

With External Virtual Switch:

• Speedtest result (I get 378 Mbps download and 212 Mbps upload) --> Speedtest.net by Ookla - My Results

• CPU usage while on Speedtest (notice the first core is fully maxed out):

• Lan Speed Test (742 Mbps upload and 596Mbps download):

• Iperf with a host on the same LAN (upload 861 Mbps, download 583 Mbps):

• CPU usage while on Iperf (download) - Notice, once again, Core 1 fully maxed out​:

Conclusion

When the External Virtual Switch is enabled, I assume the download speed is lower due to the fact one CPU core is being maxed out, my question is why? Why isn't the load spread throughout the cores?
Is anyone experiencing a similar issue?

Regards.

Slow download speed after creating Hyper-V External Virtual Switch

Have you set the number of cores to 8 in hyer-v settings (virtual processor). No idea otherwise.
