2. Adjust In-Game Settings for Maximum FPS

Why adjust in-game settings?

Higher FPS = better gameplay – Lowering certain settings can significantly improve FPS, reducing lag and stuttering.

Improved responsiveness – Higher frame rates provide better input response, which is crucial for competitive gaming.

Avoid overloading your GPU and CPU – Certain settings put unnecessary strain on the hardware, leading to overheating and performance degradation.

Key in-game settings to adjust for maximum FPS

Here are details of the most important settings you should tweak:

1. Lower graphics quality preset

Most games offer preset quality settings (low, medium, high, ultra). To increase FPS:

Start with the “Medium” preset and adjust individual settings based on performance.

If FPS is still low, try switching to lower settings to improve performance.

2. Lower the resolution
   Running the game at 1080p instead of 1440p or 4K increases FPS dramatically.
   For low-end PCs, lowering to 900p or 720p may make the game playable.
   Use resolution scaling (if available) to keep the UI sharp when rendering the game at a lower resolution.
3. Turn off anti-aliasing or reduce it
   Anti-aliasing smooths out jagged edges, but it is GPU-intensive.
   Options like MSAA, TXAA, and SSAA should be disabled or set to low.
   If necessary, FXAA or TAA are good low-impact options.
4. Reduce shadows and reflections
   High-quality shadows and reflections demand a lot of GPU power.
   Set shadows to low or medium – this gives a big FPS boost.
   Turn off ray-traced reflections and shadows if enabled.
5. Reduce texture quality (if VRAM is limited)
   If your GPU has less than 6GB of VRAM, set textures to medium or low.

If you have 8GB+ VRAM, high textures are fine, but avoid ultra settings.

6. Disable motion blur, depth of field, and bloom

Motion blur makes movement smoother, but can cause input lag. Turn it off for better clarity.

Depth of field blurs distant objects – disabling it improves sharpness and performance.

Bloom and lens flares add additional lighting effects, but affect FPS, so turn them off or reduce them.

7. Turn off V-Sync (unless needed)

V-Sync eliminates screen tearing, but increases input lag.

If you have a high refresh rate monitor (120Hz+), disable V-Sync.

Use G-Sync (NVIDIA) or FreeSync (AMD) instead for a smoother experience.

8. Lower the draw distance and environmental details

Draw distance and level of detail (LOD) control how far objects render.

Lowering these settings can improve FPS, especially in open-world games.

9. Optimize post-processing effects

Effects like ambient occlusion, SSAO, and HBAO+ enhance lighting but can reduce FPS.

Set these to low or off for better performance.

Bonus: Use an FPS optimization tool

NVIDIA GeForce Experience and AMD Adrenalin offer one-click game optimization based on your system specs.

   Benefits of overclocking:

Higher FPS and smoother gameplay – Increased clock speeds lead to better performance.
Improved game responsiveness – Reduces input lag and stuttering.
Extends hardware lifespan – Keeps older hardware relevant by squeezing out extra power.
Risks of overclocking:

Overheating – If cooling isn’t adequate, temperatures can rise dangerously.
Stability issues – Excessive overclocking can lead to crashes, artifacts, or system instability.
Warranty voiding – Some manufacturers void warranties if you overclock aggressively.
Before you begin: Make sure your PC has proper cooling (good airflow, fans, or liquid cooling) to prevent overheating.

2. How to overclock your GPU (safely)

Most modern GPUs from NVIDIA and AMD allow safe overclocking using specialized software.

Step 1: Install overclocking software

You need a GPU overclocking tool to adjust clock speeds and monitor temperatures. Recommended software:

MSI Afterburner (most popular, works with both NVIDIA and AMD)

EVGA Precision X1 (for NVIDIA GPUs)

AMD Radeon Software (for AMD GPUs)

Step 2: Increase GPU clock speed gradually

Open MSI Afterburner (or your preferred tool).

Increase core clock in small steps (10-20 MHz at a time).

Apply settings and test stability using tools like 3DMark, Heaven Benchmark or in-game testing.

If stable, increase another 10-20 MHz and repeat.

If you experience crashes, artifacts (graphical glitches) or high temperatures, stop.

Fine-tune the clock speed by lowering it little by little until it becomes completely stable.

Step 3: Increase the memory clock (optional)

Increase the memory clock 25-50 MHz at a time. Check for stability and adjust accordingly.

Step 4: Adjust power and temperature limits

Increase the power limit to 100-110% (if available).

Set the temperature limit to around 85°C (do not exceed 90°C).

Step 5: Test and monitor performance

Run a benchmark or stress test for at least 15-30 minutes.

Check for improvements in FPS and make sure the temperature stays below 85°C.

Pro tip: If you experience crashes, lower the clock speed a little bit until it becomes stable.

3. How to overclock your CPU (safely)
   Overclocking your CPU improves game performance, multitasking, and loading speeds. However, not all CPUs can be overclocked.

Step 1: Check if your CPU supports overclocking
Intel: Only “K” or “X” series CPUs (e.g., i7-12700K, i9-13900K) can be overclocked.

AMD: Most Ryzen CPUs (Ryzen 5, 7, 9) support overclocking.

Your motherboard must also support overclocking (Z-series for Intel, B/X-series for AMD).

Step 2: Install CPU overclocking software
Intel XTU (Extreme Tuning Utility) – Best for Intel CPUs.

AMD Ryzen Master – Best for AMD Ryzen CPUs.

BIOS Overclocking – Best Method for Advanced Users.

Step 3: Increase CPU Clock Speed ​​Slowly

Open Intel XTU or AMD Ryzen Master.

Increase CPU multiplier 0.1 GHz (100 MHz) at a time.

Apply settings and test stability using Cinebench, Prime95 or AIDA64.

If stable, increase it further until temperature or voltage limit is reached.

Step 4: Adjust CPU Voltage (Only if needed)

Increasing CPU voltage (Vcore) slightly can help stability, but generates more heat.

Keep Vcore below 1.35V to avoid overheating.

Step 5: Monitor Temperature and Stability

Keep CPU temperature below 85°C under load.

If crashes occur, reduce clock speed or increase cooling.

Pro tip: Instead of full manual overclocking, some motherboards offer auto overclocking (AI tweaking) for safe performance boosts.

4. Ensure safe temperatures while overclocking
   Monitor your temperatures using these tools:

HWMonitor (CPU and GPU temperatures)

MSI Afterburner (GPU temperatures and fan speeds)

CoreTemp (CPU temperatures and clock speeds)
Safe temperature ranges:

GPU: ideal = 65-80°C, max safe = 85-90°C

CPU: ideal = 50-75°C, max safe = 85-90°C
If temperatures exceed safe limits, reduce the overclock or upgrade your cooling system.

5. Should you overclock? (When it’s worth it)
   Overclocking is worth it if:

You have an unlocked CPU (Intel K/X or AMD Ryzen) and a good cooling system.

You want higher FPS in CPU-intensive games (e.g., strategy, simulation, open-world).

Your GPU is struggling in newer games and you need extra performance.

Overclocking is not recommended if:

You have a locked CPU (Intel non-K or lower-end AMD).

Your cooling system is weak (stock air coolers won’t handle it well).

Your PC is already stable, and you don’t need extra performance.

6. Final Tips for Safe Overclocking

Take small steps – to avoid overheating

Monitor temperatures – keep the CPU below 85°C and the GPU below 85°C.

Ensure proper cooling – use additional case fans or liquid cooling if needed.

Save BIOS settings – if something goes wrong, you can reset to default settings.

5. Upgrade Your Hardware (If Needed)
