Fix Ping Spikes & Input Delay – Advanced NIC Driver Tweaks

Ever wonder why your ping feels inconsistent even when your internet is fine? Or why shots feel delayed in competitive games despite high FPS? The problem might not be your ISP — it’s your network card driver. By default, Windows and NIC drivers prioritize stability over speed, adding latency, buffering packets, and spreading interrupts inefficiently. In this video, I’ll show you 5 advanced tweaks (driver settings, registry edits, and CMD commands) to reduce latency, fix ping spikes, and make your connection more responsive for competitive gaming. 🛠️ Commands & Paths Used: Step 1 – Disable Interrupt Moderation Device Manager → Network adapters → Right-click NIC → Properties → Advanced → Interrupt Moderation = Disabled Step 2 – Adjust Receive & Transmit Buffers NIC Properties → Advanced → Receive Buffers → Set 64–128 NIC Properties → Advanced → Transmit Buffers → Set 64–128 Step 3 – RSS Core Optimization NIC Properties → Advanced → RSS Queues → Set 2 (quad-core) / 4 (6–8 core) Registry Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NDIS\Parameters DWORD (32-bit): RssBaseCpu → set to least-used core index Step 4 – Disable NIC Offloads NIC Properties → Advanced → Disable: Large Send Offload (IPv4 & IPv6) TCP Checksum Offload UDP Checksum Offload TCP Segmentation Offload Step 5 – CMD & Registry Network Tweaks CMD (Run as Admin): netsh int tcp set global autotuninglevel=disabled netsh int tcp set global ecncapability=disabled netsh int tcp set global timestamps=disabled netsh int tcp set global rss=enabled Registry Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters DWORD (32-bit): TcpAckFrequency = 1 DWORD (32-bit): TCPNoDelay = 1 DWORD (32-bit): TcpDelAckTicks = 0 🚀 Steps Covered in This Guide: Disable Interrupt Moderation for instant response Reduce NIC buffer sizes for faster packet processing Optimize RSS (Receive Side Scaling) for better CPU core usage Disable useless NIC offloads to cut hidden latency Apply CMD & registry tweaks for stable, low-latency ping 💬 Found this helpful?
