[2020] Best performance?

1. Disable every option with the word "Reflection" in it.
2. Don't play at a resolution higher than 1080p. This is a Voxel game, not CSGO.
3. Ensure that your client is fully excluded from antivirus software.
4. Use DirectX. GLCore is for systems with non-supported drivers, and Vulkan is still a work in progress.
5. Double-check that your system RAM is clocked properly. Many systems over the past two years have been shipped/built with the RAM set on the lowest default for the sticks. Ensure that it is configured to use the XMP(Intel)/DOCP(AMD) profile.
6. Post exact full hardware specs so we can more specifically assist you.
Here is an example.
CPU i7-3930k overclocked at 4.6GHz
Memory 32B DDR3 RAM at 1866Mhz
GPU GTX1060 6GB SSC OC'ed a pinch over the factory OC.
DrivesOS and game saves on separate SSD's. Game client is on NVMe

OS: Win 10

Second Gen AMD CPU. Known to have poor muti-core performance. Set affinity so the client only has access to four physical cores and you should see a huge improvement.
