From 3f4fb4b0370d7dc9a0f1e7fc4b006d9f27cb5135 Mon Sep 17 00:00:00 2001 From: MerryMage Date: Tue, 21 Aug 2018 14:35:10 +0100 Subject: perf_stats: Change MAX_LAG_TIME_US to an appropriate value 25us is far too small, and would result in std::this_thread::sleep_for being called with this as a maximum value. This means that a guest application that produces frames instantly would only be limited to 40 kHz. 25ms is a more appropriate value, as it allows for a 60 Hz refresh rate while providing enough slack in the negative region. --- src/core/perf_stats.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/core/perf_stats.cpp b/src/core/perf_stats.cpp index 8e09b9b63..4e5633edb 100644 --- a/src/core/perf_stats.cpp +++ b/src/core/perf_stats.cpp @@ -76,7 +76,7 @@ double PerfStats::GetLastFrameTimeScale() { void FrameLimiter::DoFrameLimiting(microseconds current_system_time_us) { // Max lag caused by slow frames.
