Why Do Some Games Run Poorly After Updates How To Fix Lag Fast

It’s a familiar frustration: you launch your favorite game after an update, only to be greeted by stuttering frame rates, sudden crashes, or unbearable input lag. What was once a buttery-smooth experience now feels like wading through digital molasses. This isn’t just in your head—game updates can and often do degrade performance, sometimes significantly. The reasons vary from bloated code to poorly optimized patches, but the good news is that most issues can be addressed quickly with the right approach.

Understanding why performance drops happen after an update is the first step toward fixing them. More importantly, knowing which levers to pull—both in-game and on your system—can get you back to peak performance faster than waiting for a developer patch.

Why Game Updates Cause Performance Drops

Game updates are essential for security, bug fixes, new content, and balancing. But they aren’t always optimized for every player’s hardware configuration. Developers often test on high-end systems or specific setups, which means average or older PCs may struggle when new assets, scripts, or rendering techniques are introduced.

One common culprit is inefficient code. Sometimes, developers rush patches to address critical bugs or exploits, sacrificing optimization for speed. Other times, new features—like dynamic lighting, higher-resolution textures, or expanded AI routines—can inadvertently increase CPU, GPU, or memory usage beyond what older systems can handle.

Additionally, updates can reset or override custom settings players had fine-tuned over time. An update might re-enable motion blur, shadows, or anti-aliasing at high levels, dragging down performance without warning. Background processes, such as telemetry or DRM checks, may also become more aggressive in newer versions, consuming resources silently.

“Even small changes in engine logic or asset streaming can have outsized impacts on load times and frame pacing.” — David Lin, Senior Systems Engineer at PCPerf Labs

Immediate Fixes to Reduce Lag After a Game Update

You don’t need to wait weeks for a hotfix. Many performance issues can be resolved within minutes using proven troubleshooting methods. Start with these immediate actions:

1. Verify Game Files (Steam, Epic, etc.)

Corrupted or incomplete files after an update are surprisingly common. Verifying integrity ensures all components are correctly installed.

• Steam: Right-click game > Properties > Local Files > Verify Integrity of Game Files
• Epic Games: Library > Click “…” next to game > Verify
• Origin/EA App: Click the menu icon > Repair

2. Reset In-Game Graphics Settings

Updates often reset video settings to defaults, which may not match your hardware. Manually lower key settings:

• Resolution scaling (set to 90–95% if needed)
• Shadow quality (Medium or Low)
• Anti-aliasing (FXAA or TAA instead of MSAA)
• Texture filtering (Anisotropic 4x or 8x)
• Disable motion blur, depth of field, and lens flares

Tip: Use benchmark modes or replay systems to test performance changes after each setting adjustment.

3. Update Your GPU Drivers

Game updates often coincide with new DirectX or Vulkan features. GPU manufacturers release driver updates to optimize performance for newly patched titles. Visit NVIDIA, AMD, or Intel’s website to download the latest version tailored to your card.

4. Close Background Applications

Applications like Discord overlays, Chrome tabs, RGB control software, or cloud sync tools consume RAM and CPU cycles. Use Task Manager (Ctrl+Shift+Esc) to identify and close non-essential processes before launching the game.

Advanced Optimization: System-Level Tweaks

If basic fixes don’t resolve the lag, it’s time to go deeper. These system-level adjustments can reclaim performance headroom and stabilize frame delivery.

Enable High-Performance Power Plan

Windows often defaults to “Balanced” mode, which throttles CPU and GPU under load. Switch to high performance:

1. Open Control Panel > Hardware and Sound > Power Options
2. Select “High Performance”
3. For laptops, ensure “Plugged In” settings allow full processor state (100%)

Adjust Windows Graphics Settings

Windows 10 and 11 include per-app GPU preferences:

• Go to Settings > System > Display > Graphics
• Browse and add your game executable
• Set it to “High performance” (dedicated GPU)

Disable Fullscreen Optimizations

This Windows feature can interfere with modern game engines. Right-click the game’s .exe file > Properties > Compatibility > Check “Disable fullscreen optimizations.” Apply and relaunch.

Manage Page File and Virtual Memory

If you’re running low on RAM, ensure your page file isn’t restricted. Set it to “System managed size” on your SSD drive to prevent stutters during memory-heavy scenes.

Tweak	Impact	Risk Level
GPU Driver Update	High – Often resolves compatibility issues	Low
Fullscreen Optimizations Off	Medium – Improves input latency	Low
RAM Overclocking (XMP)	Medium – Better frame pacing	Medium (requires stable system)
BIOS CPU Boost Enable	High – Maximizes processing power	Medium

Case Study: Restoring Performance in “Apex Legends” Post-Update

In early 2023, a major Apex Legends update caused widespread reports of 40% frame rate drops on mid-tier rigs. Players with GTX 1660 Super cards saw average FPS fall from 90 to 55 in King’s Canyon. Respawn Entertainment later acknowledged inefficient shader compilation in the new map rotation.

One user, Mark T., a competitive player from Toronto, applied a sequence of fixes:

1. Verified game files (found 2.1GB of corrupted assets)
2. Updated to NVIDIA Game Ready Driver 528.49
3. Disabled Radeon Anti-Lag (he wasn’t using AMD anyway—residual software conflict)
4. Lowered render resolution to 90%
5. Disabled V-Sync and used NVIDIA Reflex (Low Latency mode)

Within 20 minutes, his average FPS climbed back to 85, with fewer stutters. He also noticed reduced input lag, making aim tracking noticeably smoother. This case highlights how layered issues require layered solutions—and how fast recovery is possible with systematic troubleshooting.

Preventive Checklist: Future-Proof Your Gaming Setup

Don’t wait for the next update to break your experience. Use this checklist regularly to maintain optimal performance:

• ✅ Keep GPU drivers updated monthly or after major game patches
• ✅ Monitor temperatures with tools like MSI Afterburner or HWInfo
• ✅ Clean dust from fans and heatsinks every 3–6 months
• ✅ Disable unnecessary startup programs (via Task Manager > Startup tab)
• ✅ Run disk cleanup or TRIM on SSDs to maintain read speeds
• ✅ Bookmark official patch notes to anticipate performance warnings
• ✅ Backup custom config files before updating (e.g., user.cfg, video.config)

Tip: Create a desktop shortcut to launch your game with command-line arguments (e.g., `-windowed -novid`) for faster access to optimized startup modes.

Frequently Asked Questions

Can a game update permanently damage my PC performance?

No. Game updates cannot cause physical harm to your hardware. However, poorly optimized patches can push your system to its limits, increasing heat and fan noise. Sustained high temperatures over long periods may reduce component lifespan, so proper cooling remains essential.

Why does my game lag only online after the update?

This often points to network-related changes. The update may have introduced higher tick-rate servers, increased packet frequency, or added bandwidth-heavy features like real-time voice encryption. Try switching to closer server regions, restarting your router, or using a wired Ethernet connection instead of Wi-Fi.

Should I roll back a game update if it causes lag?

Most platforms don’t support easy rollback for multiplayer games due to version mismatch risks. Single-player titles on Steam may allow beta version switching if previous builds are available. Otherwise, your best bet is applying optimization fixes until a performance patch is released.

Final Steps: When to Wait vs. When to Act

Sometimes, the best action is patience. If hundreds of players report the same issue, developers are likely already working on a fix. Check community forums like Reddit, Steam Discussions, or the game’s official Twitter for status updates.

However, never assume performance loss is inevitable. Most post-update lag stems from correctable mismatches between software expectations and system capabilities. By taking proactive steps—verifying files, tuning settings, updating drivers, and managing background loads—you regain control over your gaming experience.

The key is to act systematically. Don’t change ten settings at once. Adjust one variable, test, then move to the next. This way, you’ll know exactly what works and build a sustainable, high-performance setup that survives future updates.
