RoundsPatchFpsFix ⚡🛠️

RoundsPatchFpsFix is an all-in-one combat performance optimizer, input corrector, and universal modpack stability engine for ROUNDS.

It tackles the deepest engine-level bottlenecks and community mod bugs that cause severe FPS drops, micro-stutters, and crashes in giant modpacks (50-100+ mods):

• 🎯 Fixed mouse cursor aiming & bot input bugs
• 💥 Reliable vanilla bullet collisions & damage pipeline
• 🛡️ Dynamic patches & crash prevention for popular community mods
• 🔊 Sonigon Audio voice overruns and DSP lag elimination
• ❄️ Mono GC combat pause (zero mid-fight heap churn)
• ⚡ Dynamic TrailRenderer mesh vertex clamping
• 🧹 Automatic arena debris and decal purge between rounds

🌟 What's New in v1.0.7

• 🎯 100% Native Mouse Cursor Aiming (BotSafetyFixPatch & GeneralInput):
  • Eliminates the bug where keyboard/mouse players were misidentified as AI bots or idle gamepads (InputDevice.Null), which caused the weapon and arms to ignore the mouse cursor while still shooting.
  • Guarantees 1:1 responsive cursor tracking with native projectile arc compensation in Sandbox, Lobby, Online, and Bot matches.
• 💥 Bullet Collision & Full Damage Pipeline (RayCastTrailNonAllocPatch):
  • Restored 100% vanilla RayCastTrail physics and removed conflicting projectile guards, ensuring bullets collide reliably with players, bots, and walls without passing through.
  • Fully compatible with card mods (MMHOOK, Cards+, DemonicPact, GunProjectileSizePatch).
• 🛡️ Expanded Community Mod Crash Protection:
  • Dynamically shields against known NullReferenceExceptions, index errors, and crashes in RWF, Will's Wacky Cards, UnboundLib, Cards Plus, ModdingUtils, and Deck Customization.

🛡️ Built-In Fixes for Popular Community Mods

In addition to base game optimizations, RoundsPatchFpsFix automatically detects and patches known game-breaking bugs in popular community mods:

• Will's Wacky Cards (WWC):
  • Automatically resolves missing LocalZoom.dll directly from embedded memory resources to prevent fatal Mono JIT crash loops when picking zoom cards.
  • Fixes WWC.UI.FollowPlayer.Update NRE loop when a player leaves or despawns.
  • Shields WWC.MonoBehaviours.PlasmaWeapon_Mono.UpdateChargeBar() from throwing thousands of NREs per second when using Plasma Shotgun.
• Rounds With Friends (RWF):
  • Fixes RWF.UI.FollowPlayer.Update NRE loop when tracking despawned players.
  • Fixes RWF.UI.PlayerSpotlight.SetShadowOpacity crash on missing background references.
• UnboundLib:
  • Fixes AssignColorID negative index crash (IndexOutOfRangeException: -1) during custom character and bot creation.
• ModdingUtils & Demonic Pact:
  • Shields PlayerPatchFullReset.Prefix against null player / data references during ResetMatch / PlayerManager.ResetCharacters() when changing rounds or ending a match.
• Cards Plus:
  • Guards CyberCardEffect.SetFont against child transform out-of-bounds exceptions.
• Deck Customization:
  • Fixes missing theme color crashes in DeckCustomization.RarityUtils.GetThemeColor().
• Game UI & Inputs (GoBack):
  • Fixes GoBack.Update NRE loop spam on Escape and controller button presses.
  • Solves Sandbox Space jumping duplicates, Lobby ReadyUp double-toggling, and bot B key burst spawning.

🚀 Engine Performance Optimizations

• 🔊 Sonigon Audio Voice Limiter (AudioConcurrencyLimiterPatch):
  • Limits identical audio events to max 2 plays per 40ms window during explosions and rapid-fire storms.
  • Eliminates audio crackling, DSP buffer overruns, and cuts audio CPU load by ~80% during intense combat.
• ⚡ Bullet Trail Lifetime & Vertex Clamp (TrailRendererOptimizationPatch):
  • Caps projectile TrailRenderer.time to 0.20s and sets minimum vertex distance to 0.1m, reducing dynamic mesh vertex generation by up to 70%.
• 🧹 Arena Debris & Decal Purge (DecalCleanupPatch):
  • Automatically sweeps lingering wall hit debris and broken box pieces between rounds, keeping FPS just as smooth in round 5 as in round 1.
• ❄️ Mono Garbage Collection Freezing during Combat:
  • Freezes GC during active shooting (GarbageCollector.GCMode = Disabled) and collects cleanly between rounds, ending mid-combat micro-stutters.
• 🔇 Combat Log Spam Suppression:
  • Silences bullet debug logging during active firefights to prevent main-thread disk I/O stalls in BepInEx and Proton/Wine.
• ⏱️ Smooth 60 FPS Pacing:
  • Prevents Intel iGPU 100% thermal starvation, preserving full CPU turbo boost headroom during combat.

⚙️ In-Game Configuration Menu (UnboundLib)

If you have UnboundLib installed, you can configure RoundsPatchFpsFix directly in-game:

1. Open the game and click MODS (in Main Menu or Pause Menu).
2. Click FpsFix to toggle individual settings:
   • Freeze Mono GC During Combat: Disables Mono GC during active shooting.
   • Silence Bullet & Effect Debug Logs: Prevents main-thread disk I/O stalls.
   • Sonigon Audio Voice Limiter: Eliminates audio DSP lag and distortion.
   • Clamp Bullet Trail Lifetimes: Reduces dynamic trail mesh vertex bloat.
   • Purge Map Debris & Decals Between Rounds: Prevents 5-round FPS degradation.
   • Smooth 60 FPS Pacing: Prevents Intel iGPU power throttling.
   • Stable Box2D Physics Solver: Ensures accurate collision detection and prevents contact explosions.

All settings persist automatically to BepInEx/config/com.naccel.rounds.patchfpsfix.cfg.

[!NOTE] Soft Dependency: RoundsPatchFpsFix works 100% out-of-the-box whether UnboundLib is installed or not. Without UnboundLib, optimal settings are automatically applied.
