From 938c90fd3bd2bba920d35f112aca445f293a46d8 Mon Sep 17 00:00:00 2001 From: Thorsten Ball Date: Fri, 6 Sep 2024 15:35:00 +0200 Subject: [PATCH] Revert FPS counter (#17485) **UPDATE**: Response so far seems to be that this fixes the performance issues on Intel MacBooks. So we're going to go ahead and merge it. This reverts the FPS counter added in 11753914d (#16422) because in this issue someone bisected recent performance regressions down to this commit: - https://github.com/zed-industries/zed/issues/16729 Another issue that's possibly related: - https://github.com/zed-industries/zed/issues/17305#issuecomment-2332316242 We're reverting this in a PR to create a bundle that people can try out. Assets: - Universal Binary: https://github.com/zed-industries/zed/actions/runs/10735702994/artifacts/1900460781 - x86/Intel: https://github.com/zed-industries/zed/actions/runs/10735702994/artifacts/1900461236 - Apple Silicon: https://github.com/zed-industries/zed/actions/runs/10735702994/artifacts/1900460978 Release Notes: - Removed the recently-added FPS counter since the changes it made to the Metal renderer on macOS could lead to performance regressions on Intel MacBooks.
