I had no idea any of this stuff worked well enough to actually run modern games. The FEX emulation layer. The eGPU. It's not how fast this stuff runs that impresses me, it's that it runs at all.
FEX is very impressive.
Box64 was there first
RTX 5090 and Raspberry Pi: Can it game?

Re: RTX 5090 and Raspberry Pi: Can it game?
#42I think the conclusion here is that Raspberry Pis are now too pricey (especially when factoring in the various required accessories) and rarely make sense for typical desktop use vs. x86 mini-PCs. They make even less sense compared to various used thin clients that can generally be found on eBay.
It would make a lousy desktop computer even if it was 10x as powerful. - high current 5V USB power supply you probably don't have - HDMI micro port you have like 1 cable for - PCIe through very fragile ribbon cable + hodgepodge of adapters - more adapters needed for SSD - no case, but needs ample airflow - power input is on the side and sticks out GPIO is the killer feature, but I'll be honest, 99% of the hardware ha…
> PCIe through very fragile ribbon cable
We had a problem trying to bring up a couple of Pi 5, hoping they'd represent something reproducable we could deploy on multiple sites as an isolation stage for remote firmware programming. Everything looked great, until we brought one somewhere and untethered it from ethernet, and we started getting bizarre hangs. Turned out the wifi was close enough to the PCIe ribbon cable that bursts of wifi broadcasts were enough to disrupt the signal to the SSD, and essentially unmount it (taking root with it). Luckily we were able to find better shielded cables, but it's not something we were expecting to have to deal with.

#43This is a funny project. Too many people taking this serious, it is more of a 'can it be done' because the physical interfaces suggest that it should be possible, and then to follow through on it to prove that yes it actually can be done. And tbh much better than I expected it to work. I can imagine that for GPU compute heavy and interconnect bandwidth constrained applications a combination like this might actually b…
i thought my post was already too long to include this, but to your point, you can run AI inference in this setup and the performance can be pretty good.
There are definitely some use cases where it works out, others where it doesn't; I spent a bit of time testing that side of things late last year: https://www.jeffgeerling.com/blog/2025/big-gpus-dont-need-bi...

#44> Cyberpunk barely hits 16 FPS average on the Pi 5. This is a lot better than my memories of forcing a Pentium MMX 200 MHz PC with 32 MB SDRAM and an ATI All-in-Wonder Pro of running games from the early 2000s.
There's more comparisons with various Arm hardware and Cyberpunk 2077 over here: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...
The DGX Spark and Mac Studio are currently the two best Arm-based platforms for running that game, it seems to like a lot of CPU to feed a decent GPU.

#45The radxa SBC has gen3 X4 ?!?!...holy hell. Would have guessed X1
Interesting

#46Earlier quoted context omitted.
Denuvo is DRM, not anticheat.
Denuvo isn’t quite DRM either. It’s an anti-tamper layer; the whole goal being to prevent the binary from modifications. This then prevents the DRM of choice (ie Steamworks) from being bypassed. I know that sounds a little pedantic; but typically DRM involves an identity layer (who is allowed to access what?). Denuvo doesn’t care about that; it’s even theoretically possible to make a Denuvo protected binary anyone co…

a great post that definitely inspired this one. i link to it in the first paragraph of my blog post.

> I think the conclusion here is that Raspberry Pis are now too pricey
This blog post shows a $2000 GPU attached to a slow SBC that costs less than 1/10th of the GPU.
It’s interesting. It’s entertaining. It’s a fun read. But it’s not a serious setup that anyone considers optimal.
Re: RTX 5090 and Raspberry Pi: Can it game?
#49The more interesting metric is running HL2 on Pi4, Pi5 and 3588:
Pi4: 20 FPS same when using ffmpeg to stream to twitch. 5W
Pi5: 40 FPS idem as above. 10W
3588: 300+ FPS and rock solid 60 FPS streaming to twitch. 15W
So 5090 is not even interesting for gameplay. More polygons and larger textures do not make games more fun to play.
AAA has peaked and C++ does not even deliver interesting games any more. C#/Java are way better alternatives for modding.

it's extra funny to me because the Raspberry Pi SoC is basically a little CPU riding on a big GPU (well, the earlier ones were. Maybe the latest ones shift the balance of power a bit). In fact, to this day the GPU is still the one driving the boot sequence.
So plugging a RasPi into a 5090 is "just" swapping the horse for one 10,000x bigger (someone correct my ratio of the RasPi5 GPU to the RTX5090)
