v1.5.4 - DPS Refresh Rate Settings

Release Notes - Version 1.5.4

Release Date: 2025-12-13

New Features

⚡ DPS Refresh Rate Settings

Description: Customizable DPS meter update frequency to balance performance and smoothness based on your PC specs and preferences.

Problem Solved: Users reported lag when tabbed into the game during combat. The DPS meter was competing with the game for CPU/GPU resources, causing frame drops and stuttering. When tabbed out, the meter worked smoothly because the game wasn't actively rendering.

Solution:

• Added configurable refresh rate with 4 preset options
• Minimal: 10 FPS (100ms refresh) - Best for low-end PCs or when playing in-game
• Low: 20 FPS (50ms refresh) - Good balance between smoothness and performance (Default)
• Medium: 30 FPS (33ms refresh) - Smooth updates, moderate CPU usage
• High: 60 FPS (16ms refresh) - Maximum smoothness, highest CPU usage (high-end PCs only)

Implementation:

• Created DpsRefreshRate.cs enum with extension methods for FPS/interval conversion
• Modified DpsStatisticsViewModel.cs to use dynamic UI update throttle based on user setting
• Updated BattleLogQueue.cs to support global batch timeout configuration
• Added GlobalBatchTimeout property that syncs with UI refresh rate
• Increased default batch size from 100 to 300 for better throughput
• Added OnDpsRefreshRateChanged handler in AppConfig.cs to update queue timeout dynamically

UI Location:

• Settings → Performance → DPS Refresh Rate
• Dropdown with 4 options (Minimal/Low/Medium/High)
• Detailed tooltips explaining each option
• Changes take effect immediately without restart

User Impact:

• Eliminates lag when playing in-game - Lower refresh rates reduce CPU competition with the game
• Customizable smoothness - Choose higher rates when tabbed out or on powerful PCs
• Instant feedback - No restart required, change settings mid-combat
• Recommended Settings:
  • Playing with game focused: Minimal (10 FPS) or Low (20 FPS)
  • Monitoring while tabbed out: Medium (30 FPS) or High (60 FPS)

Performance Improvements

🚀 UI Thread Optimization

Description: Improved UI responsiveness during intense combat by changing sorting operations from blocking to non-blocking.

Technical Change:

• Changed _dispatcher.Invoke() to _dispatcher.BeginInvoke() with Background priority in DpsStatisticsSubViewModel.cs
• Sorting operations no longer block the UI thread
• UI remains responsive even during heavy combat with many players

Impact:

• Smoother UI interactions during raids and World Boss Carnage
• Reduced stuttering when many players are in combat
• Better overall application responsiveness

⚡ Batch Processing Optimization

Description: Increased BattleLogQueue batch size from 100 to 300 for better throughput.

Impact:

• More efficient processing of combat logs during intense fights
• Reduced queue backlog during high-activity scenarios
• Works in conjunction with configurable refresh rates for optimal performance

Bug Fixes

🐛 Fixed ScopeTime Toggle Not Working (Current ↔ Total)

Issue: When switching from Current to Total damage view, it worked correctly. However, switching back from Total to Current would fail to update the UI, leaving the meter stuck showing total damage.

Root Cause: The OnScopeTimeChanged handler was calling UpdateData(), which went through the throttled update path designed for combat data updates. When users manually toggled between Current/Total, the UI update would be delayed by the DPS refresh rate throttle (10-100ms depending on settings) or skipped entirely if a pending update was already scheduled.

User Report: "when I switch from current damage to total it works, but then switching back to current doesn't work"

Fix Applied:

• Modified OnScopeTimeChanged() in DpsStatisticsViewModel.cs (lines 1049-1071)
• Changed from UpdateData() to PerformUiUpdate() to bypass throttling
• Modified OnStatisticIndexChanged() to use the same approach for metric switching (lines 1073-1086)
• User-initiated actions now update immediately without throttle delay
• Combat data updates continue to use throttling for performance

User Impact:

• ✅ Current ↔ Total toggle now works instantly in both directions
• ✅ Metric switching (Damage/Healing/TakenDamage) updates immediately
• ✅ No performance regression - combat updates still throttled as designed
• ✅ Better responsiveness to manual UI interactions

🐛 Reduced Boss Death Delay

Issue: After defeating a boss, the meter would continue tracking for too long (8 seconds) before archiving the fight as "Last Battle."

Fix Applied:

• Reduced BossDeathDelaySeconds from 8 to 5 in DataStorageV2.cs
• Combat now archives 3 seconds faster after boss death

User Impact:

• Faster transition to "Last Battle" state after boss fights
• Meter stops tracking sooner when combat truly ends
• More responsive meter behavior at the end of encounters

Files Changed

Added

• BlueMeter.WPF/Models/DpsRefreshRate.cs
  • New enum with 4 refresh rate options (Minimal, Low, Medium, High)

  • Added DpsRefreshRate property (default: Low = 20 FPS)
  • Added OnDpsRefreshRateChanged handler to update BattleLogQueue timeout (lines 290-295)
  • Automatically syncs refresh rate with queue batch processing

• BlueMeter.WPF/ViewModels/DpsStatisticsViewModel.cs

  • Changed _uiUpdateThrottle from constant to computed property (line 70)
  • Now calculates throttle dynamically: UiUpdateThrottle => TimeSpan.FromMilliseconds(AppConfig.DpsRefreshRate.GetIntervalMs())
  • Updated throttle checks to use dynamic property (lines 349, 355)
  • Improved comment documentation for UI update throttling

• BlueMeter.WPF/ViewModels/DpsStatisticsSubViewModel.cs

  • Changed _dispatcher.Invoke() to _dispatcher.BeginInvoke() (line 98)
  • Added DispatcherPriority.Background for sorting operations (line 120)
  • Moved UpdateItemIndices() inside BeginInvoke block for consistency
  • Added comment explaining non-blocking UI approach

• BlueMeter.WPF/Views/SettingsView.xaml

  • Added new "Performance" section with CardHeader (lines 898-901)
  • Added DPS Refresh Rate dropdown ComboBox (lines 906-933)
  • Binds to AppConfig.DpsRefreshRate with TwoWay binding
  • Added detailed info text with FPS explanations for each option (lines 936-955)
  • Used bullet points (• symbol) for clear visual hierarchy

• BlueMeter.Core/Data/BattleLogQueue.cs

  • Added GlobalBatchTimeout static property for UI-controlled timeout (line 36)
  • Changed _batchTimeout from readonly to mutable field (line 25)
  • Added UpdateBatchTimeout() method for runtime changes (line 40)
  • Modified constructor to respect GlobalBatchTimeout if set (line 56)
  • Increased default batchSize from 100 to 300 (line 50)
  • Default timeout remains 50ms if not overridden

• BlueMeter.Core/Data/DataStorageV2.cs

• Protected list creation in cached list properties
• Protected dictionary modifications and clearing operations

Impact

• Eliminates crashes during extended play sessions with multiple consecutive encounters
• Minimal performance overhead from locking
• Fixes instability in high-activity scenarios (raids, World Boss Carnage)

Files Changed

• BlueMeter.Core/Data/DataStorage.cs - Added thread synchronization

Special Thanks

• GitHub user anguyen2015 for reporting the crash with detailed error logs

v1.4.6

BlueMeter v1.4.6 - Critical Bug Fixes

Release Date: December 8, 2025
Branch: main
Status: ✅ Released

---

🐛 Critical Bug Fixes

Meter Freeze After Timeout Fix

Fixed critical issue where the DPS meter would remain frozen and stop accepting new combat data after a timeout occurred followed by a manual reset.

Root Cause:

• When combat timeout occurred, _timeoutSectionClearedOnce flag was set to true
• Manual reset via ResetData() or ResetFullData() did not reset this flag
• Meter remained in "timeout cleared" state, blocking all new data ingestion
• Only way to recover was to wait for new battle logs to trigger a section change

Impact:

• Users experiencing timeouts had to restart BlueMeter to get meter working again
• Manual reset button became ineffective after any timeout
• Severely impacted user experience in long play sessions

Solution:

• Added _timeoutSectionClearedOnce = false reset in both ResetData() and ResetFullData() methods
• Wrapped in proper _sectionTimeoutLock synchronization
• Meter now immediately accepts new data after manual reset, regardless of previous timeout state

Files Changed:

• BlueMeter.Core/Data/DataStorageV2.cs (Lines 954-962, 1108-1116)

Technical Details:

// CRITICAL FIX: Reset timeout flag to allow meter to accept new data after manual reset
// Without this, if timeout occurred before reset, meter stays frozen until new battle logs arrive
lock (_sectionTimeoutLock)
{
    _timeoutSectionClearedOnce = false;
}

---

Plugin Enable/Disable Logic Fix

Fixed issue where only the DPS Plugin was enabled, blocking access to all other plugins including History, Settings, etc.

Root Cause:

• Previous code: public bool IsEnabled => Plugin.GetType().Name == "DpsPlugin";
• This hardcoded check disabled all plugins except DpsPlugin
• Users could not access Chart History, Advanced Settings, or other features

Solution:

• Changed to: public bool IsEnabled => Plugin.PackageName != "BlueMeter.WPF.Plugins.BuiltIn.ModuleSolverPlugin";
• All plugins now enabled except Module Solver (intentionally disabled - under development)
• Restores full functionality of all production-ready plugins

Files Changed:

• BlueMeter.WPF/ViewModels/PluginListItemViewModel.cs (Line 37)

---

✨ User Experience Improvements
