  • Single GPU with scripts that run before and after the VM is active to unload the GPU driver modules from the kernel.

    I think this was my starting point and I had to do just a few small tweaks to get it right for my setup - i.e. unload and reload the precise set of kernel modules that block GPU passthrough on my machine.

    At this point from a user experience p.o.v it’s not much different to dual booting, just with a different boot sequence. The main advantage though is that I can have the Windows OS on a small virtual harddrive for ease of backup/clone/restore and have game installs on a dedicated NVME that doesn’t need backing up

    I’ve been 100% linux for my daily home computing for over a year now… With one exception… To be honest I didn’t even try particularly hard to make gaming work under Linux.

    Instead I have a Windows VM - setup with full passthrough access to my GPU and it’s own NVME - just for Windows gaming. To my mind now it’s in the same category as running console emulation.

    As soon as I click shutdown in windows, it pops me straight back into my Linux desktop.











  • Just to add in case you’re not aware, the EF-RF adapters are literally just spacers that shift the lens mount to where it would have been if there was a mirror in there - optically it’s just 24mm of air, so no quality impact at all.

    The only thing to keep in mind is that there is a slight autofocus slow-down with the much older lenses, but not enough to bother me.

    I literally just faced this same dilemma! I went online looking to upgrade the kit lens I’ve had on my Canon EOS 70D for nine years and got sucked into the mirrorless hype.

    In the end I sortof ended up upgrading both… I got a great deal on a second hand Canon mirrorless body, and because it has in-body image stabilisation I could then spend a lot less money to get a 25 year old ‘L’ series EF lens rather than a newer one with IS in the lens.

    I’m extremely pleased with this set-up so far, and even more pleased that I can add to my lens collection in future for much less money than if I needed IS hardware in every lens.




  • I agree it’s good that the article is not hyping up the idea that the world will now definitely be saved by fusion and so we can all therefore go on consuming all the energy we want.

    There are still some sloppy things about the article that disappoint me though…

    1. They seem to be implying that 500 TW is obviously much larger than 2.1 MJ… but without knowing how long the 500 TW is required for, this comparison is meaningless.

    2. They imply that using more power than available from the grid is infeasible, but it evidently isn’t as they’ve done it multiple times - presumably by charging up local energy storage and releasing it quickly. Scaling this up is obviously a challenge though.

    3. The weird mix of metric prefixes (mega) and standard numbers (trillions) in a single sentence is a bit triggering - that might just be me though.
