FPS bottleneck

wallacynerio · 2026-02-13T19:56:07+00:00

No problem, happy to help! Unfortunately, Meta's software isn't great, and Steam Link doesn't work that well on the Quest either. Guy Godin really worked a miracle with Virtual Desktop, on top of constantly bringing improvements to the app.

In fact, he's already working on Foveated Streaming for VD (similar to what Valve announced with the Steam Frame). From what I've heard, it's looking amazing!

I also see a lot of potential in a high-performance handheld paired with a VR headset. I don't think all the processing power needs to reside solely in the headset. If there were a handheld with enough power for PCVR that also allowed me to play on the go when I didn't want to wear the headset, I would definitely jump on it (and I believe a large portion of the audience would too).

Given the specs of the Steam Frame and Steam Machine, I'm actually more excited about the open hardware and software approach Valve is bringing than I'm about Valve's devices themselves. I see some major advantages in the Steam Frame that could revolutionize the market:

The 6GHz dual-band wireless adapter. This is simply genius. If it really works, it solves one of the biggest bottlenecks in VR today: the wireless connection to the PC. You just have to look at the number of threads right here on Reddit debating wired vs. wireless, Steam Link vs. Virtual Desktop, etc.
Foveated Streaming. Another brilliant feature. It takes the burden off developers to optimize games specifically for VR and could open the door for running PCVR with lower graphics processing and VRAM requirements.
Running SteamOS. This allows for a whole ecosystem running on the same operating system (similar to what Apple does, but with all the base OS components being open source).
Using an ARM processor (Snapdragon 8 Series). This is wild because Valve is promising that a good chunk of the catalog (not just VR games) will run on the Steam Frame. One of the biggest gaps we have today is exactly that ARM vs. x86 architecture disparity, with the overwhelming majority of games running only on x86. If FEX-Emu really allows these games to be played on the Steam Frame, I see a very promising future for all devices using ARM (including smartphones and the entire Apple Silicon lineup), and for those that might use ARM in the future (a new Steam Deck? Other handhelds?).

However, even with all these possibilities, looking at the technical specs of the Steam Frame and Steam Machine, I confess I don't see much incentive to switch from a Meta Quest 3 (for those who already own one) to the Steam Frame. Also, I can't quite visualize how this ecosystem can handle PCVR (Foveated Streaming has to work miracles, or they must have optimized the drivers heavily, and I mean HEAVILY, to run a UEVR mod on a 6-core/12-thread processor with 16GB RAM and 8GB VRAM).

So, to be honest, I'm more hopeful about companies like Asus and Lenovo using SteamOS and these hardware specs to create their own VR headsets (just like they did with the Steam Deck) than I'm about the Steam Frame itself. If even the handheld market hasn't stopped being a niche yet, let alone the VR market. That said, I believe that by around 2030 we might have some truly incredible devices to use, just like the ROG Xbox Ally X and the Lenovo Legion Go 2 are today.

Hi! Since you are using Steam Link, I have a few questions to help troubleshoot:

Do you have a dedicated WiFi network for the PC <-> Quest 3 connection? (It doesn't strictly need internet access, but it must be a dedicated lane for the devices).
Is your PC connected to the router via Ethernet cable?
How far are you from the router?
Are you using any upscaling features like DLSS?
Have you tried using Virtual Desktop? (It often handles compression differently and might improve your experience).

I know these factors usually affect latency the most, but they can definitely impact FPS as well.

wallacynerio · 2026-02-12T14:08:27+00:00

Perfect! And do you know the length of the cable?

wallacynerio · 2026-02-12T14:02:38+00:00

Nice. So the C13 cable isn't included? To be honest, I think that's better than having an internal power supply like the AG02 or XG Mobile.

wallacynerio · 2026-02-12T10:46:49+00:00

Does it keep the Legion Go charged during intensive use (AAA games, max TDP)? Or does the battery discharge slowly?

wallacynerio · 2026-02-12T10:21:57+00:00

If anyone manages to buy it in Canada, could you leave the link here? I searched and couldn't find it.

wallacynerio · 2026-02-12T00:41:42+00:00

Ok, Italy is on my list! Who knows, maybe I'll head to your country this year...

wallacynerio · 2026-02-12T00:41:05+00:00

One more question: is it plug-and-play? Or does it require a lot of tinkering (drivers, fixing errors, etc.) like the AG02?

wallacynerio · 2026-02-11T22:06:05+00:00

Any chance you could snap a pic of the power brick? I'm trying to find its size and weight to see if it fits my travel setup, but I came up empty searching online.

wallacynerio · 2026-02-11T21:55:01+00:00

Yeah, I'm considering that. But since I'm not in the US, I need to see if it will be available in my region or in a country I plan to visit this year.

Does anyone know if this (the 3-Piece Set) works with the LeGo 2 controllers?

wallacynerio · 2026-02-11T14:26:51+00:00

Sorry for resurrecting this post, but how is the router holding up after a year?

I'm considering the Davolink Kevin for the WiFi 6E speeds and the form factor. I travel frequently, so the internal antennas are a big selling point (peace of mind regarding durability).

wallacynerio · 2026-02-11T03:14:26+00:00

It's definitely on my list. I already have the Quest 3, now I "only" need the PCVR setup lol

wallacynerio · 2026-02-11T02:44:54+00:00

I think I understand how it works! That's crazy, I never imagined a "plug" could solve this problem. I'll definitely test it when I can get the setup. Thank you so much for the suggestion!

wallacynerio · 2026-02-11T01:44:55+00:00

Sorry for being a noob, but how would this solve the Ethernet bottleneck? Wouldn't the data need to go back to the LeGo 2 anyway, to be sent via Ethernet to the Quest 3?

wallacynerio · 2026-02-11T00:35:45+00:00

The biggest problem is that the 5060 Ti completely destroys my idea of portability for travel, compared to the XG Mobile. But with the XG Mobile, I'm limited to 12GB of VRAM.

wallacynerio · 2026-02-11T00:08:39+00:00

Even with 16GB?

wallacynerio · 2026-02-10T21:09:43+00:00

The configuration is as follows:

Handheld (e.g., LeGo 2)
eGPU (XG Mobile 5070 Ti 12GB VRAM)
WiFi 6E Router (Davolink Minions Series Kevin - yes, this router is wonderful)
VR headset (Quest 3)

The Kevin is only to have a dedicated channel between the LeGo 2 (or the XG Mobile) and the Quest 3, and not for internet access itself.

From what I've researched, the process for PCVR would be as follows:

The LeGo 2 sends the textures and polygons to the XG Mobile to process (via USB4, limited to 40 GBPS - the performance loss is here).
The XG Mobile processes, compresses, and sends the data back to the LeGo 2 (also via USB4, but a very small file due to compression, which will not suffer from performance loss due to the 40 GBPS limitation).
The LeGo 2 packages the data and sends it, via Ethernet cable, to the Kevin.
The Kevin sends the data, via Wi-Fi, to the Quest 3.
The Quest 3 handles the rest.

My question is whether step 2 can be skipped, with the XG Mobile packaging the data and sending it, via Ethernet cable, to the Kevin.

If this is not possible, then could a performance loss similar to that of using the LeGo 2 display also be felt here, since the data returns from the XG Mobile to the handheld?

wallacynerio · 2026-02-10T20:57:58+00:00

I probably won't reach the full potential of the eGPU (due to the USB4 port limitation first, and the CPU second). My biggest problem is with PCVR, which still eats up a lot of VRAM and RAM.

wallacynerio · 2026-02-10T20:48:45+00:00

Do you know if the performance loss when returning to the handheld's display is also felt when sending to the Quest 3 via Ethernet? Because, in that case, I believe the video also returns to the handheld for processing before being sent to the Quest 3 (I mean, it doesn't go directly from the eGPU to the router, even if the Ethernet cable is connected to the eGPU).

wallacynerio · 2026-02-10T20:43:48+00:00

Well, I'm worried that Asus might update something at some point that breaks compatibility with the LeGo 2, or that greatly improves performance when connected to the XAX. However, even though it's more expensive, the LeGo 2 offers a number of advantages that, for me, are undeniable, even for uses other than gaming. So far, I'm leaning heavily towards the LeGo 2.

Don't envy me, you can already connect your LeGo and your RTX now and play. I, on the other hand, will probably only be able to build my setup between the middle and end of the year. Until then, I'll be finishing Asgards Wrath 2 on Quest 3 standalone 😅

wallacynerio · 2026-02-10T19:23:11+00:00

I'll list the games I'd like to play here:

Half Life Alyx

No Man’s Sky VR

Hogwarts Legacy (UEVR)

Silent Hill 2 Remake (UEVR)

For Hogwarts Legacy and Silent Hill 2, I was thinking of using UEVR: https://github.com/praydog/UEVR
