From 762b8ad448369cc770beae4d8368a6258b13709e Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Thu, 2 Dec 2021 14:20:43 -0500 Subject: [PATCH] general: Replace high_resolution_clock with steady_clock On some OSes, high_resolution_clock is an alias to system_clock and is not monotonic in nature. Replace this with steady_clock. --- src/common/x64/native_clock.cpp | 6 +++--- src/core/hle/service/audio/hwopus.cpp | 4 ++-- src/core/perf_stats.h | 4 ++-- src/video_core/shader_notify.cpp | 2 +- src/video_core/shader_notify.h | 2 +- src/yuzu/loading_screen.cpp | 4 ++-- src/yuzu/loading_screen.h | 4 ++-- 7 files changed, 13 insertions(+), 13 deletions(-) diff --git a/src/common/x64/native_clock.cpp b/src/common/x64/native_clock.cpp index 87de406240..28f8344439 100644 --- a/src/common/x64/native_clock.cpp +++ b/src/common/x64/native_clock.cpp @@ -19,16 +19,16 @@ u64 EstimateRDTSCFrequency() { // get current time _mm_mfence();
