I love Vultr High Frequency 2GB RAM NVMe for game servers! It's fantastic and fits your budget perfectly.

• Guaranteed high clock speeds
• Low latency networking
• Cost-effective pricing model

I have been thinking about your setup for a few hours now. Re: "I love Vultr High Frequency 2GB RAM NVMe..." - honestly, while Vultr is usually okay for personal stuff, I have found their performance consistency can be a bit hit or miss during peak hours. In my experience over the years, game servers like OpenClaw are incredibly sensitive to what we call noisy neighbors. If someone else on your physical host starts a heavy task, your game frame times will spike and cause that stuttering. Dont risk it for a tournament. Since you have a tournament this Friday, I would personally steer you toward a more stable platform. I have tried many providers, and for a $15 budget, I would recommend DigitalOcean Premium Intel 2GB 1 vCPU 50GB NVMe or even Hetzner Cloud CPX21 3 vCPU 4GB RAM AMD EPYC. Here is why these are safer bets:

• Improved Architecture: The DO Premium droplets use newer Intel Xeon Scalable processors. This is huge for preventing those micro-stutters.
• Network Stability: In my experience, the network stack at DO and Hetzner tends to be a bit more predictable for gaming. You want low jitter, not just low ping.
• Resource Overhead: Hetzner gives you a ton of raw power for the price. Having those extra cores means the OS wont steal cycles from your game thread as much. Basically, you want to minimize any chance of CPU steal. Vultr HF is fast, but it can be erratic when the host is crowded. I would go with the DigitalOcean Premium Intel 2GB 1 vCPU just to be safe for the competition. Im around if you need more help with the config tho.
