⚡ パフォーマンスのヒント

🎯

Competitive FPS Settings

Lower shadow quality and anti-aliasing first. These have minimal impact on competitive play but free up significant GPU resources.

⚡

High Refresh Rate Priority

For competitive shooters, aim for 144+ FPS. Consider a 144Hz or 240Hz monitor for smoother gameplay.

🗺️

VRAM Matters

Open world games use lots of textures. Aim for 8GB+ VRAM for High textures at 1080p, 12GB+ for 1440p Ultra.

👁️

View Distance Settings

Reducing view distance can significantly improve FPS with minimal visual impact during normal gameplay.

🚀

Enable DLSS/FSR

If Just Cause 3 supports DLSS (NVIDIA) or FSR (AMD), enable it for 30-50% performance boost with minimal quality loss.

🔄

Update GPU Drivers

New games often get Day-1 driver optimizations. Always update to the latest GPU drivers before playing.

🌡️

Monitor Temperatures

Use MSI Afterburner to monitor GPU temps. Keep below 85°C for optimal performance and longevity.
