Emulator Issues #7000
closedCache Display Lists is completely incompatible with NVIDIA Buffer Storage
0%
Description
This affects all games. Any modern NVIDIA card will produce garbled, destroyed graphics when using cache display lists alongside Buffer Storage.
Previously with the Vertex Streaming Hack, this was not an issue.
I'm not entirely sure what should be done with the option. It does provide a small boost to some games, but considering it completely breaks pretty much every game on modern NVIDIA cards, there needs to be some way to help users not trigger this. I accidentally did and spent a while figuring out. Options are:
- Figure out a way to disable Cache Display Lists when Buffer Storage is used
- Remove the Cache Display List option because it has minimal effects at best + it's a hack and neobrain hates those.
- Do nothing and torment the forum mods as they answer a bevy of questions from frustrated users
- Add a warning to the tooltip
I'm sure there are other options, I just wanted to provide mine.

let me guess, our dl cache reads back from the streaming buffer? This isn't allowed on many apis ...
So if we want to keep our dl cache, we have to set up a fake buffer and memcpy there (like we always did)

It apparently breaks on Radeons as well.

I don't know how the fuck the display list cache has even stayed in Dolphin for so long, it breaks shit all over the place. LET'S REMOVE IT

I agree with the removal, for me this hack always seemed to bring more problems than benefits. It should also help clean the codebase a little bit.
