[1.19.4] Shader Performances

As I've come to note, Iris seems to have some if not most shaders perform worse.

Example, Complementary Reimagined!

Runs at 180 - 210 on Optifine.
Runs at 140 - 160 on Sodium/Iris

It's a strange thing, As Sodium gives more vanilla FPS as a whole. What all could be happening here?

AMD Ryzen 7 5800X
AMD Radeon RX 6700 XT
24GB 3200 DDR4 [4 ALLOCATED]

There are other optimization mods that can improve framerates, namely lithium and starlight. Install those first for a fair performance comparison, since sodium only improves rendering performance and optifine tries to do everything.

Otherwise make sure you're actually using the same settings (both in video settings and in the shader pack settings)

Mithos•6/1/23, 7:24 AM

If that doesn't work I can only say: every hardware configuration is different and some perform better with optifine, most perform better with iris. It's important to try both and figure out which one runs better on a given system

That's weird tho, I had a 5800X/6700XT and 32 GB 3600 MHz for a while and iris performed way better, so it can't be the hardware that doesn't work well with iris

Well if you could send F3 screenshots that could help

But one thing I could think of is that Optifine loads chunks a lot slower, so it might not have reached your target render distance while Iris did

This is BSL

why are you not using vsync

Watermelonn•6/9/23, 8:36 AM

and you're getting 144+fps and saying it's laggy

asu•6/9/23, 9:13 AM

they didn't say it's laggy... and the comparison is with one shaderpack...

Mithos•6/9/23, 12:53 PM

it's definitely maxing out your GPU, so I'm not sure why optifine would perform better. Did you test both in the same scene and same version?

hysteria•6/9/23, 5:48 PM

Did you try again after installing starlight and lithium?
Starlight in particular, its not needed anymore in 1.20 but if youre still on 1.19.4 it makes a noticeable difference with the lighting system
Lithium will probably improve cpu performance more than anything so it likely wouldnt affect your current problem
definitely try with starlight, and perhaps also have a go with immediatelyfast

I utilize lithium and starlight*

Deleted UserOP•6/9/23, 5:59 PM

It's probably just a hardware thing

Deleted UserOP•6/9/23, 6:08 PM

One moment

DDeleted User It's probably just a hardware thing

hysteria•6/9/23, 6:12 PM

perhaps, though the hardware itself shouldnt have any issues especially if its working in optifine
i also use complementary reimagined primarily, which if any other performance related mods other than optifine are you using?
I can test it on my system as well and see if the performance is any different

Deleted UserOP•6/9/23, 6:13 PM

Using default optifine [since 1.20 doesnt have a forge version yet] and sodium with lithium and immediatelyfast

Deleted UserOP•6/9/23, 6:14 PM

BSL is EXTREMELY prominent

Deleted UserOP•6/9/23, 6:14 PM

Depending on scenario at least

hysteria•6/9/23, 6:14 PM

which version of BSL? The latest?

Deleted UserOP•6/9/23, 6:17 PM

Im starting to consider it may be more scenario based

Deleted UserOP•6/9/23, 6:17 PM

Having switched to 1.20 has seemingly put iris [reimagined] above optifine in more situations compared to .4

hysteria•6/9/23, 6:18 PM

well, you can test it
generate a new world with a preset seed
spawn in, dont move and just check framerate
do the same on both optifine/sodium installs and wait a minute or two for average fps to stabilize

Deleted UserOP•6/9/23, 6:18 PM

Well I do already have a completely empty world

Deleted UserOP•6/9/23, 6:19 PM

Deleted UserOP•6/9/23, 6:19 PM

Optifine

Deleted UserOP•6/9/23, 6:19 PM

Sodium

Deleted UserOP•6/9/23, 6:19 PM

Oh hang on

Deleted UserOP•6/9/23, 6:19 PM

Mismatched the packs

Deleted UserOP•6/9/23, 6:19 PM

Deleted UserOP•6/9/23, 6:20 PM

There

Deleted UserOP•6/9/23, 6:20 PM

Not too different

Deleted UserOP•6/9/23, 6:20 PM

Likely not even noticeable

Mithos•6/9/23, 6:20 PM

this looks like within variance

Deleted UserOP•6/9/23, 6:20 PM

hysteria•6/9/23, 6:20 PM

quite similar, and GPU utilization makes sense as wel

MMithos this looks like within variance

Mithos•6/9/23, 6:21 PM

basically no difference, fps fluctuates a little all the time

hysteria•6/9/23, 6:21 PM

188fps @ 98%
177fps @ 91%
looks like just fluctuation
if the difference is noticeable, I would recommend perhaps capping your fps lower at something like 150 which both installs can hit consistently
