+# GhostRider (Raptoreum) release notes
+
+**XMRig** supports GhostRider algorithm starting from version **v6.16.0**.
+
+No tuning is required - auto-config works well on most CPUs!
+
+**Note for Windows users: MSVC binary is ~5% faster than GCC binary!**
+
+### Sample command line (non-SSL port)
+```
+xmrig -a gr -o raptoreumemporium.com:3008 -u WALLET_ADDRESS
+```
+
+### Sample command line (SSL port)
+```
+xmrig -a gr -o us.flockpool.com:5555 --tls -u WALLET_ADDRESS
+```
+
+You can use **rtm_ghostrider_example.cmd** as a template and put pool URL and your wallet address there. The general XMRig documentation is available [here](https://xmrig.com/docs/miner).
+
+## Performance
+
+While individual algorithm implementations are a bit unoptimized, XMRig achieves higher hashrates by employing better auto-config and more fine-grained thread scheduling: it can calculate a single batch of hashes using 2 threads for parts that don't require much cache. For example, on a typical Intel CPU (2 MB cache per core) it will use 1 thread per core for cn/fast, and 2 threads per core for other Cryptonight variants while calculating the same batch of hashes, always achieving more than 50% CPU load.
+
+For the same reason, XMRig can sometimes use less than 100% CPU on Ryzen 3000/5000 CPUs if it finds that running 1 thread per core is faster for some Cryptonight variants on your system. Also, this is why it reports using only half the threads at startup - it's actually 2 threads per each reported thread.
