The "8GB not enough" thread

[CP5670]

I did pick up HL Alyx for $24 on the Steam sale. It is a good looking game but it has a ton of quirks. I can't help myself by going on a rant about this game.

On launch I see a warning about low VRAM usage, but game had textures pre-set to ultra. Past few hours I've been on high textures, and it has used around 7.8 to 8.9 GB of VRAM use. I would argue 3080 is fine for this game as long as you use a budget HMD.

I am seeing around 60-80% GPU usage at 5408x2736 (native) at a locked 120fps at 120hz. But at 2x supersample I can start any mission with max VRAM usage. Even if FPS counter says 100-110, it feels choppy.

Like any PCVR game on Quest 2, I gotta run the Oculus Debug Tool to disable Asynchronous Spacewarp and Adaptive GPU Performance Scale. Then in Alyx I gotta run -console -vconsole +vr_fidelity_level_auto 0 +vr_fidelity_level 3 to disable resolution scale feature.

Adding -nowindow will provide an enormous performance uplift by disabling Spectator Window. This allows me to run GPU at just 1.5 GHz and draw 140W while playing this game at a smooth 120.

Game has another layer of Asynchronous Spacewarp inside which is simply awful and made me want to refund it. This will arbitrarily cut a users framerate to half their refresh rate if the game thinks CPU or GPU usage is too high. Reading how setting hlvr.exe priority to high will help minimize this. Process Lasso will help remember that for me. There is no such thing as intelligent ASW in my opinion. It will still often cap fps to 60 during main menu and loading screens though.

You can just ignore that warning, I get it on any video card but the game works fine. Maybe try running it at 90hz instead of 120hz. It never went into reprojection for me at 90hz, even on a 1080ti or 3090. 200% supersampling is probably too high in this game given that it's already vram hungry.

The warning is just a bug that is shown to everyone, even people with a 3090 and 24 GB of VRAM.

The game actually works very well on lower-end hardware, but it does seem that they didn't make it scale to more high end hardware all that well. Although a 3080 is hardly truly high-end for VR.

Looks like it will try to use upwards of 16 GB even at lower resolutions if the card has it. It's pretty clear that it wants this much as if you look at the system memory utilization the 8 GB cards like the 3070 or 6600 XT had to allocate around twice as much RAM.

It doesn't seem like the cards with less memory are seeing significant performance degradation as a result, but more focused testing to look specifically for that would be necessary. I'm assuming the game is loading as much data as possible to speed up zone transitions, waypoints, etc.

Rename the thread to: The "20GB not enough" thread?

I can live with 16GB Vram for some time, so let's change It to "12GB not enough" thread.

Honestly speaking, buying RTX 4090 Laptop over RTX 4080 doesn't make much sense unless you want 16GB Vram.


Difference in SM count is 76(131%) vs 58(100%), but difference in frequency is 28-30%.

Mobile N32 could be interesting because of 16GB Vram, but It will be certainly slower than ADA104.
