| Summary | Pinned memory is extremely slow on Dolphin |
| Product | Mesa |
| Version | git |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | normal |
| Priority | medium |

When running Dolphin with the OpenGL backend and pinned memory enabled, I get terrible performance. Getting about 10-20fps in a 60fps game with pinned memory, and full 60fps without it. This was discussed on dolphin's IRC channel earlier today, and this PR was made to disable it. If it gets committed you'll have to use a build without that code to test it I think. https://github.com/dolphin-emu/dolphin/pull/4973/commits/005e6796b85341a3e79fc93e49337bb8d4e67fdf I'm using an RX460, Linux 4.10.0, mesa/llvm/xorg-server all built from git, although it happens on older stable versions too.
