  • Consider using a game booster software (but research carefully)

Official Resources and Support

If you’ve tried all the above solutions and PUBG still won’t launch, consider these official resources:

For Vietnamese players experiencing specific regional issues, you might find helpful information on the Ministry of Information and Communications of Vietnam website regarding internet connectivity and gaming regulations.

Alternative Solutions for Vietnamese Players

Players in Vietnam sometimes face additional challenges due to regional network configurations:

  1. Use a VPN: Some players report better connectivity using a VPN service. However, be aware that:
    • Using VPNs might violate PUBG’s terms of service
    • Some VPNs can increase ping rather than decrease it
    • Free VPNs often have data limits and security risks
  2. Change DNS Settings:
    • Press Win+R, type “ncpa.cpl” and press Enter
    • Right-click your active network connection and select “Properties”
    • Select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties”
    • Select “Use the following DNS server addresses”
    • Try Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1)
  3. Check ISP Restrictions: Some Vietnamese ISPs may throttle gaming traffic. Contact your ISP to ensure they’re not limiting your connection to gaming servers.
  4. Use Local Servers: In the PUBG settings, try connecting to Asian servers (like Korea or Japan) which might provide better routing from Vietnam.

Performance Comparison: HDD vs SSD in PUBG

Your storage type significantly impacts PUBG’s loading times and performance:

Metric HDD (7200 RPM) SSD (SATA) NVMe SSD
Game Load Time 60-90 seconds 30-45 seconds 20-30 seconds
Texture Loading Frequent stuttering Minimal stuttering No noticeable stuttering
Map Loading Slow, buildings pop in Faster, fewer pop-ins Very fast, minimal pop-ins
FPS Stability More frame drops More stable FPS Most stable FPS
Price (500GB) $20-$40 $50-$80 $80-$150

Based on this comparison, upgrading to at least a SATA SSD can provide significant performance improvements in PUBG, especially in loading times and texture streaming.
