From a62b11606e75b579fa2086b5f191c251f54b41f2 Mon Sep 17 00:00:00 2001 From: Dean Herbert Date: Sat, 17 Jun 2023 01:32:41 +0900 Subject: [PATCH] Attempt to fix NaN fps display The only thing I can see which could cause this is reading from the `drawClock.ElapsedFrameTime` after the `isSpike` read causing a div-by-zero. Reading the values once at the start should avoid this. --- osu.Game/Graphics/UserInterface/FPSCounter.cs | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/osu.Game/Graphics/UserInterface/FPSCounter.cs b/osu.Game/Graphics/UserInterface/FPSCounter.cs index 9dbeba6449..c1ef573848 100644 --- a/osu.Game/Graphics/UserInterface/FPSCounter.cs +++ b/osu.Game/Graphics/UserInterface/FPSCounter.cs @@ -167,9 +167,12 @@ namespace osu.Game.Graphics.UserInterface { base.Update(); + double elapsedDrawFrameTime = drawClock.ElapsedFrameTime; + double elapsedUpdateFrameTime = updateClock.ElapsedFrameTime; + // If the game goes into a suspended state (ie. debugger attached or backgrounded on a mobile device) // we want to ignore really long periods of no processing. - if (updateClock.ElapsedFrameTime > 10000) + if (elapsedUpdateFrameTime > 10000) return; mainContent.Width = Math.Max(mainContent.Width, counters.DrawWidth); @@ -178,17 +181,17 @@ namespace osu.Game.Graphics.UserInterface // frame limiter (we want to show the FPS as it's changing, even if it isn't an outlier). bool aimRatesChanged = updateAimFPS(); - bool hasUpdateSpike = displayedFrameTime < spike_time_ms && updateClock.ElapsedFrameTime > spike_time_ms; + bool hasUpdateSpike = displayedFrameTime < spike_time_ms && elapsedUpdateFrameTime > spike_time_ms; // use elapsed frame time rather then FramesPerSecond to better catch stutter frames. - bool hasDrawSpike = displayedFpsCount > (1000 / spike_time_ms) && drawClock.ElapsedFrameTime > spike_time_ms; + bool hasDrawSpike = displayedFpsCount > (1000 / spike_time_ms) && elapsedDrawFrameTime > spike_time_ms; const float damp_time = 100; - displayedFrameTime = Interpolation.DampContinuously(displayedFrameTime, updateClock.ElapsedFrameTime, hasUpdateSpike ? 0 : damp_time, updateClock.ElapsedFrameTime); + displayedFrameTime = Interpolation.DampContinuously(displayedFrameTime, elapsedUpdateFrameTime, hasUpdateSpike ? 0 : damp_time, elapsedUpdateFrameTime); if (hasDrawSpike) // show spike time using raw elapsed value, to account for `FramesPerSecond` being so averaged spike frames don't show. - displayedFpsCount = 1000 / drawClock.ElapsedFrameTime; + displayedFpsCount = 1000 / elapsedDrawFrameTime; else displayedFpsCount = Interpolation.DampContinuously(displayedFpsCount, drawClock.FramesPerSecond, damp_time, Time.Elapsed);
