LOD gap with terrain when using shaders (1.21 no tag yet)

I was using on MC 1.20.4 DH 2.1.0-a + iris 1.7.0 and photon shaders, I preload the LOD on singleplayer and transfer the LOD in the server folder, everything was fine. But now I'm on 1.21, DH 2.1.2 (also had the issue with nightly build) with Iris 1.7.1 and it's behaving a bit differently. When I'm using the shaders there is a gap between the terrain (32 chunks) and the LOD (128). It doesn't appears everywhere, but most of it. I flew away for a trial chamber and flying back to my base, I had the same issue despite having covered the region to be sure I had load everything manually.

Yes 1.21 is out. Check Curseforge or Modrinth.

If this happens when you are flying/moving fast, there is not a lot you can do. Vanilla chunk loading simply can't keep up. If this also happens when standing still, you'll need to tweak overdraw prevention in your shader's settings if you shader has that setting

It happens when flying but also when flying slowly, but that's weird because I never had this issue on the previous version

did you use shaders on the previous version?

Yep, same as now. I made a copy of my instance and updated the mods for 1.21 so all config files remain the same Just in case, I do have Bobby, Nvidium, Sodium, C2me and a couple of others

c2me is useless now it slows dh generation a bit

it is not, it speeds up vanilla chunks loading speed it might help with overdraw a bit

but slow down dh

The problem on the screen shot is that vanilla chunks can't keep up, not that DH chunks can't keep up, so using C2ME here is advised

yeah but that's not what i am talking about

Shaders also slow down generation a bit Yet people are using them If you don't want to reduce vanilla RD, the only other thing you can do is reduce the overdraw prevention in shader's settings

Unfortunately Photon shader doesn't have this option but I tried with Bliss and the result is really similar I can try with reducing the vanilla RD then
