Terrible performance - CPU not at 100%
Fair is fair, I know Source is a very CPU intensive engine, and I'm stuck using an FX 8150.
However, neither CPU nor GPU are reaching 100% usage - in fact, they are at a steady 40% - , and I see my FPS dipping to 40 and 20s. In some parts of Xen - specially around Gonarch's Lair - it goes down to single digits.

I know I'm not having temp issues, drivers are all to date and everything, and tinkering with the graphic settings has yielded only some results dropping everything to potato.

So what can I do to enjoy this game without hating Source for being what it is?

What frequency is your CPU set to?

Stock at 3600, all overclock settings disabled.
Much as I'd like to overclock, the system becomes very unstable, even just pushing it at 3900.

Hold on to your pants. I think I found the issue.
I know I said temp wasn't a problem, but leaving the game and coming back to it after some time vastly improved performance, if only for a little while.

Turns out, the thermal compound of my GPU was practically dust.
For once, it wasn't a CPU-related issue with Source.

Don't use cheap thermal paste boys.

Irony.

Yes, source is very CPU intensive. You can try Vulkan API

Considering there are many other posts with similar issues, it didn't and still doesn't seem farfetched to point fingers. Even now after I thought I fixed the issue, I'm still having a spectacularly sketchy performance - If anything, I'm running out of fingers to point with.

Is my GPU overheating? The sensor doesn't agree, but it's also a wonderful 35ºC in here.
Is Source hot garbage? Yes, but also my CPU is halfway to a driving licence.

But I suppose at least you find some amusement in this.
I'm off to try the Vulkan API.

First time performance can be worst, when dxvk compile shaders, but later performance will stabilize
Esta piola el juego, pero siento q le re cambiaron muchas cosas q te quedas O-O y esta mas dificil :;C:steamhappy:

No luck with Vulkan - game crashes on launch.
im running it on a 1660 super and sometimes i get massive FPS drops, usually when im doing something stupid like in the processing plant area i threw a bunch of barrels onto the solid waste disposal belt with the idiot mindset hey maybe i can jam up that ♥♥♥♥♥♥♥ grinder in this game, instead like 5 barrels just piled up in front of it and started nearly vibrating from the interaction with the grinder. had to platform the whole way back up (fell down) at 9fps and remove the barrels one by one. sometimes the steam overlay with messages does it too it seems

the fx was bad when it came out and its especially bad now

also, you never want your cpu at 100% while gaming as that means your cpu cant keep up with the gpu and you'll get stutters.

I managed to get Vulkan working - albeit with some caveats; the menu overlay doesn't work at all, though that is somewhat circumvented with the handy 'resume last saved game' button in the main screen.

The previous Nvidia drivers I was using (497), probably had some issues, though I can't confirm this since simultaneously I realized that launching the game with MSI Afterburner/Riva Tuner open (also?) resulted in an instant crash.

I'll test for a bit and report whether Vulkan does better than DX9, at least for my setup.
Ice Jan 14 @ 7:28pm 
Alright. Here's what I can surmise:
No substantial difference using Vulkan or DX9
Riva Tuner wrongly reports the FPS count - whereas the Steam overlay was correctly depicting situations ranging in 30/40/60 fps, Riva Tuner was about 120/200/400 fps.
Riva Tuner also seems to struggle with DX9, for some reason. In the overlay, you can see the video wrapper label constantly flick between DX9 and Vulkan.

More generally speaking, I'm fairly sure the issue with Black Mesa is video-based, which I can confirm by simply looking away from the main center of the map. Looking at an empty exit can yield around 300 FPS, looking back into the more iconic scenes of Interloper can kick it down to 20.

Fiddling with the settings doens't yield any significant change. High settings may eat a few more frames, but going down to potato doesn't solve the issues.
