Performance issues running HL:A - game reboots my computer

[John_F-in_Lennon]

I'm at wits end. I'm encountering severe issues with Half Life: Alyx.

I played about half the game with no issues, only minor stuttering and FPS drops. Then, around level 7, things went haywire. Massive choppiness, unplayable framerates. I looked up some guides online for fixes. Did some of those, and now the game runs *okay* on lowest settings, but every time I die and have to reload a save file, the game conks out and my computer reboots, which is insane.

I can play a few minutes fine, but eventually the game becomes choppier and choppier and I either save and quit out or the game crashes.

The thing is, I have an out of the box Dell Ryzen G15. Haven't used it for anything else, the only time it connected to the internet was to download Steam and to update the drivers. Here are my specs:

AMD Ryzen 7 5800H 8-core/16-thread Mobile Processor

NVIDIA GeForce RTX 3050 Ti 4GB GDDR6

16GB DDR4 3200MHz

On paper, this computer should have no problems running any VR games. I got through Boneworks fine with sporadic slowdowns in open spaces, but the game worked okay (I was disappointed with the performance given this machine's specs, but at least it worked).

I'm playing with an Oculus Quest 2 headset plugged into my machine with a USB cable.

I updated all drivers, as well as the BIOS. I also tried various fixes found on forums, like allocating virtual memory space etc.

Any ideas?

Honestly if its actually rebooting, that would lead to it being a hardware issue. (usually a psu issue). Now I understand its an out the box, but that does not mean its right, things happen.

What is the wattage of PSU that is supplied? Maybe under full load its simply not keeping up.

With it being a laptop it could also be heat related. What are your temps, It could be thermal throttling hence it plays for a little bit, then slows, then resets.

Some people with similar issues have improved things with a full driver strip out and re-install, but it has not fully resolved the issue.

As for performance I should point out that maybe your expectations are a little off, the 3050 while new is a low-mid range card and it only has 4gb of vram, which will hold it back, essentially your using a series 30 model 50, and the mobile version at that (which are usually slower than their desktop counterparts).

Doing a google search it seems a few people are having issues with G15's resetting.

If its under warranty I would contact Dell customer support and explain the issue. Just looking through that thread, it would appear to be a hardware issue. Though not the psu as I thought, apparently when boosting the cpu to play games better, its sending too much power.

I am not sure if its doing that in your case, but it is looking more like an issue with the g15 hardware. So contacting Dell maybe your only way forward.

Ceejay hes using a laptop. Also try using air link and see if that fixes it.

I've had exactly the same experience, started the game with a 1070ti and was playable, up until level 7 in the hotel, then it became a choppy mess. Have upgraded to a 3070ti and it's made absolutely no difference to the performance. Am using a Quest 2 with USB cable.

It's possible your battery consuption is too low for the specs, what is your wattage?
