Is using AMD GPU and CPU a bad idea for SFM?

[Turgineer]

Two weeks ago I bought a computer with AMD RX 6600 and Ryzen 5500.

When I first open the map, I get 180 FPS. While moving the arm of the character in Motion Editor (all render settings is off) it drops to 12 FPS, if I move the arm with "rig_biped_simple" it drops to 2 FPS. Even my old Intel HD Graphics computer didn't have that much of a drop. Is this an AMD related issue?

Please let me know if there is a solution.

I have a Ryzen 7 processor and SFM works normally on it, so I doubt that it has anything to do with AMD specifically. I will point out that I run nvidia gfx and have for years, so the video card might have something to do with it, but again, unless it's a built-in gpu, I don't think that this would be an issue either.
It's probably more likely the age of the program showing.
SFM is 32 bit, and by it's very nature has issues that other, more modern software doesn't have.
SFM also has not seen an official update since about 2015, if I'm not mistaken.
Valve seems to have no real interest in updating it or rewriting it to bring it up to current technology specs, so we're stuck with it, or some other animation software that is out there...

Yes, Blender is increasing AMD support with updates, but SFM is abandoned software.

If the problem is not AMD related, that would make me happy, but I still don't know how to fix the problem. Trying to animate with 2 FPS is very difficult.

Maybe the AMD driver couldn't detect SFM or incorrect GPU setting on SFM specifically. I can't help you with this particular issue because I'm using gaming laptop with Nvidia GPU.

I think I remember that Zappy (a popular regular here) has AMD GPU. Maybe they can help you better. Best to wait.

It seems logical to me that there may be a problem with the drivers. Graphics card usage drops below 4% in FPS drops.

I have an NVIDIA GPU, and I don't know anything about this issue.
All I know is that Source Filmmaker's ambient occlusion supposedly looks different on AMD and NVIDIA GPUs, and that (as long as you use a "good enough" GPU,) Source Filmmaker is typically limited by single-core CPU performance.
Like you, all I can suggest is double-checking that Source Filmmaker is using the correct GPU (if the computer has both integrated and discrete GPUs).

This might sound dumb, but is your monitor plugged into the graphics card or the motherboard?

I am using Ryzen 5500 and this processor does not have integrated graphics.

Since it's not one of those familiar SFM errors, two things come to mind. The driver is faulty or turned off AMD's automatic CPU Overclocking(CPB) was bad idea.

I struggled with this ridiculous problem for a few months and gave up. But, last week, I deleted my AMD driver because it gave an error and I switched to the Pro driver, which was said to be more stable and same FPS with Adrenalin.

I can now use HIP in Blender and SFM is very smooth.

I can't believe I haven't tried Pro drivers all this time. Darn...

Pro drivers are more stable.
