    Based on how you’re observing the loading move from 100% CPU ro 100% GPU, I would suggest that it is “working” to some extent.

    I don’t have any experience with that GPU, but here’s few things to keep in mind with this:

    1. When you use a GPU for video encoding, it’s not the case that it’s ‘accelerating’ what you were doing without it. What you’re doing is switching from running a software implementation of an HEVC encoder on your CPU to running a hardware implementation of an HEVC encoder on your GPU. Hardware and Software encoders are very different to one another and they won’t combine forces; it’s one or the other.

    2. Video encoders have literally hundreds of configuration options. How you configure the encoder will have a massive impact on the encoding time. To get results that I’m happy with for archiving usually means encoding at slower than real-time for me on a 5800X CPU; if you’re getting over 100fps on your CPU I would guess that you have it setup on some very fast settings - I wouldn’t recommend this for anything other than real-time transcoding. Conversely, it’s possible you have slower settings configured for your GPU.

    3. Video encoding is very difficult to do “well” in hardware. Generally speaking software is better suited to the sort of algorithms that are needed. GPUs can be beneficial in speeding up an encode, but the result won’t be as good in terms of quality vs file size - for the same quality a GPU encode will be bigger, or for the same file size a GPU encode will be lower quality.

    I guess this is a roundabout way of suggesting that if you’re happy with the quality of your 100fps CPU encodes, stick with it!

    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.

    There are a LOT of waterfalls in Iceland, that much is true, there just wasn’t any point on that trip where I had the slightest inclination to go camping - a lot of it is very exposed with very little in the way of natural shelter or facilities. Our typical day when we went was four or more hours of driving with maybe two or three amazing points of interest en route. The vast open space in between was stunning in it’s own way too, but there’s a lot of it.

    There may well be some part of Iceland that’s ideal for backpacking, the West Fjords maybe now I think about it, but then you’d be missing out on what the rest of that incredible place has to offer if you hop in a car.

    Most of my camping experience is in the UK. If you’re lucky with the weather, wild camping in the west of Scotland is extraordinary. After a two day drive and a ferry crossing we once had the most magical night camping at a white sand beach on Vatersay in the Outer Hebrides on what was supposed to be the first night of an epic bikepacking adventure… The next day the rain was so bad we aborted the trip. Back on the mainland the NC500 is legendary.

    Alternatively, we had a great backpacking trip once interailing around Europe. No camping, just cheap accommodation in towns/cities en route. If you’re young an interail ticket is quite economical. We did Paris, Zurich, Milan, Nice/Monaco, Barcelona and Toulouse among other smaller towns on a 10 day trip.

    On my bucket list is to bikepack mainland Europe. There are some quite famous routes and the vycle paths in countries like Netherlands and Germany are very good quality.

    Boat hopping and wild camping around the Croatian islands is another one a friend of mine has done and enjoyed.

    So many options, not enough time - even for us based closer!

    To answer your question directly, I have an MSR HUBBA HUBBA 2 and would recommend it as a great piece of kit for the money, if perhaps slightly over your ideal budget.

    However, as both a keen camper and having been to Iceland myself, I’m not sure what you propose sounds like a good idea to me. Iceland is a pretty sparse place once you get beyond the ‘Golden Circle’, and in September average temperatures are between 5°C and 10°C (about 41°- 50° Fahrenheit). Backpacking with a tent is going to be very cold and you’re likely going to miss out on seeing a lot of the island.

    In my experience there are two good approaches to exploring Iceland. Firstly you can base yourself in Reykjavik and focus on exploring the ‘Golden Circle’. This is easily achievable by coach day trip(s) from Reykjavik. Secondly, you can hire a car from the airport and do a lap of Route 1. This way you’ll break free from the most well trodden tourist sites and see a broader array of landscapes and places of interest.

    The joy of camping is a great thing to want to share with your wife, but a sparse, cold island formed primarily out of volcanic rock isn’t the right starting point; if getting into backpacking is an important goal for your September break I suggest you consider mainland Europe instead.
