That just means it's using the vanilla rendering api and not the fabric rendering api, it wouldn't cause the issue
Having a very similar experience, originally thought it may have been my resource packs but even with them disabled and everything else set to the minimum settings I've been experiencing serious FPS drops (lowest I've seen was 7, but it quickly hopped back up to 9). It averages 13 and gets the worst when I try to turn or look up- down isn't as low as the other directions.
EDIT: Wanted to mention that it will start out great at about 60-70 fps with shaders and the works, 80-90 with just Iris, Fabric and Origins. However, after roughly 30 minutes into gameplay (no matter whether on a server or a single player world) it starts to tank into the previous mentioned drops.
It seems Sodium has a leak and Iris itself has a few might want to check both vram and ram.
Edit: With a GT710 you will hit that limit fast.
@coderbot16 maybe add something like sodium issue or ... Forgot what it was called I'll come back with a edit.
Edit: Don't we already have a issue on Iris leaks so shouldn't this be moved to the sodium repo, or closed as duplicated?

So I played last night and decided to take some screenshots from when it tanks. I attached the logs as well. I tested it without the other mods- just Iris and Sodium and it still has the same issues so I didn't bother screenshotting them. The screenshots include the mods:
- Iris/Sodium,
- LambsDynamicLights,
- OkZoomer,
- Origins/Extra Origins/Fabric
- ShulkerBoxToolTip
- ModMenu
- Music Reducer
- Pehkui
The texture/resource packs I am using are:
- Better Visibility of Ores
- Better Clear Glass
- Colorful Flora
- Kal's Armor
- Pride Axolotls
- Visible Ores
- A Vanilla Tweaks pack
I was playing for four hours at this point (from roughly 9 pm to 1 am, give or take) with Complementary Shaders on and it was running at an average of 45 fps, 75 fps without shaders. I stayed within a 70 chunk radius (working on two builds side by side, they span roughly 300 blocks in a square?) This was right before I turned the shaders off as it became unplayable:
It worked for the twenty or so minutes and then this happened:
When looking back at the logs (attached at bottom), I mainly saw these issues:
- *[STDRR] No uniform exists with name (ex. u_ModelViewMatrix).
- *[] Unsupported uniform: float/mat4/vec3 (one of those 3 and then a similar or matching name to above) (this one and the one above begin anytime I start the CS pack and happens a lot. Not sure why but that's why I'm not a programmer)
- *Shader could not find sampler named in the specified shader program. (this one varies quite a bit.)
- Ignoring draw buffer 9 from draw buffers array [0, 5, 9] since Iris doesn't support extended color buffers yet.
- Received passengers for unknown entity (.....Yeah no clue. Starts about 30 minutes in.)
- *Failed to parse the block ID map entry There is no block with the name ! (It's calling on a bunch of plants. Going to completely honest here, this is partially why I included the list of mods and textures because I have no idea where these are coming from)
*Happens the most
There will also be a few errors about simple voice chat, its on the server but I don't have it; it's never been an issue and when I don't have Iris/Sodium running it's fine. It isn't the mods nor is it the server (we use Shockbyte, but it does this offline as well). My computer has ran these mods and more with no issue, so it's not a hardware issue either. I plan on trying different shaderpacks to see if certain parts of certain packs are causing conflicts or if its just a pack-wide thing.

It definitely doesn't help, that's for sure. I've also noticed that loading animals or mobs doesn't trigger it? It seems to just progressively get worse over the course of two minutes.
Once again, the issue is being fixed, it was an issue with a mem leak that is being patched by both the sodium and iris team actively, and the next release should solve all these issues
