CUSA03173 Bloodborne: Dark spots in the DLC only happening on Intel cpus #1594

Open Missake212 opened 1 day ago

Missake212 commented 1 day ago

While looking around in the DLC, I noticed what I would qualify as weird black/dark spots, at first glance I could tell it wasn't this way on real hardware. Here's how it looks on my game: Capture d'écran 2024-11-19 055744

And here's how it looks like on real hardware (couldn't get a screenshot since I can't go online on my ps4): GcubCF1WoAAJCFS

Intrigued, I asked around in the BB channel if people were willing to go there and check for themselves, and I quickly noticed a pattern. My rig has an Intel cpu (13900k) and an Nvidia gpu (4090), I asked brad from the discord if he could test and here's how it looks for him (he has an AMD 5600x and an Nvidia 2080 Super): zzzzz

Seeing this we can tell that it appears to render normally on systems with AMD cpus. I asked for some more testing and here are the results I got from the Discord, black means the textures appear black and dark, normal means it renders like the game on original hardware: Capture d'écran 2024-11-25 101408

I don't know why exactly this issue appears on system with Intel cpus, also it's not like the sfx issue where it affects only 12th, 13th and 14th gen, it also affects older intel cpus. I want to add that I've tested multiple different builds, some with tess, some without, and the issue always happened for me, so I'm pretty sure it's a hardware issue. I noticed more spots in the DLC where this issue happens, though I didn't go further than Ludwig myself, so there's maybe even more, and I also didn't really check the base game to see if this also happens outside of the DLC. Here are a few more examples of those dark textures: Capture d'écran 2024-11-23 010015 Capture d'écran 2024-11-23 010023 Capture d'écran 2024-11-23 010031 Capture d'écran 2024-11-24 174114 Capture d'écran 2024-11-24 174448 Capture d'écran 2024-11-24 174518 Capture d'écran 2024-11-24 174541

Finally, following brad's suggestion, I tried to see if removing baked lights would maybe have an effect on the issue, and it seems he was right. Here's how it looks like with the baked lights removed, it sometimes kind of solve the issue, but some other times make everything black: Capture d'écran 2024-11-24 202727 Capture d'écran 2024-11-24 202756 Capture d'écran 2024-11-24 202619 Capture d'écran 2024-11-24 202636 Capture d'écran 2024-11-24 202557

Also, shining a light source, such as the player's light or a torch for example seems to make the darkened texture display a little bit closer to real hardware: Capture d'écran 2024-11-23 010306 Capture d'écran 2024-11-23 010303 Capture d'écran 2024-11-24 174114 Capture d'écran 2024-11-24 174151

Here are a few more screenshots from brad (with his amd cpu): qzdzqdzqdzqqzddzq gdfgdfgfdg hjkjhkjhkjhkjh

If you find any more spots, whether in the DLC or in the base game, feel free to share your screenshots here, don't know if there's much the devs can do about this, and I'm sure there's many other issues that should be taken care of first before this one, but I wanted to post about it anyway, hoping that more people are aware of it and don't open a new issue with barely any valuable information, or ask the devs and contributors in the help channel about it.

Yes, there is such a problem. 1 2

It turns out something like there is not enough light source... The hair of dogs is also.

I also have some kind of ripples on the textures or whatever it is, I don't know what to call it correctly.

Yeah I noticed those two issues (the dog's hair and the flickering on the ground) but I'm not sure if all these issues are related or not.
