Hi,

First, I want to thank all of you for the work you’re doing. It has made so much possible for so many people.

Do you have any insight into if this is a limitation of WLS, or perhaps the existing memory space can be resized?

Any further enhancements in WSL2 cuda performance done (or planned) since this update a year ago. Very much looking forward to using it when it gets closer to native Linux. Thx!
