From c1b7340023b42161d55993de2e40baad68915b86 Mon Sep 17 00:00:00 2001 From: jduncanator Date: Mon, 29 Oct 2018 09:31:13 +1100 Subject: Timing: Optimize Timestamp Aquisition (#479) * Timing: Optimize Timestamp Aquisition Currently, we make use of Environment.TickCount in a number of places. This has some downsides, mainly being that the TickCount is a signed 32-bit integer, and has an effective limit of ~25 days before overflowing and wrapping around. Due to the signed-ness of the value, this also caused issues with negative numbers. This resolves these issues by using a 64-bit tick count obtained from Performance Counters (via the Stopwatch class). This has a beneficial side effect of being significantly more accurate than the TickCount. * Timing: Rename ElapsedTicks to ElapsedMilliseconds and expose TicksPerX * Timing: Some style changes * Timing: Align static variable initialization --- Ryujinx.HLE/HOS/Kernel/KCoreContext.cs | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'Ryujinx.HLE/HOS/Kernel') diff --git a/Ryujinx.HLE/HOS/Kernel/KCoreContext.cs b/Ryujinx.HLE/HOS/Kernel/KCoreContext.cs index 51f27e2a..02354e16 100644 --- a/Ryujinx.HLE/HOS/Kernel/KCoreContext.cs +++ b/Ryujinx.HLE/HOS/Kernel/KCoreContext.cs @@ -1,3 +1,4 @@ +using Ryujinx.Common; using System; namespace Ryujinx.HLE.HOS.Kernel @@ -25,7 +26,7 @@ namespace Ryujinx.HLE.HOS.Kernel if (Thread != null) { - Thread.LastScheduledTicks = (uint)Environment.TickCount; + Thread.LastScheduledTicks = PerformanceCounter.ElapsedMilliseconds; } if (SelectedThread != CurrentThread) -- cgit v1.2.3
