Yes, in your test, the RAM usage should be ~250 MB, not 950, no matter the settings (at least if your download is only one file). This point is highly suspect, but not necessarily linked to the delays. For the rest, I am perplexed. I hope the author of the driver will have a better idea. About the RAM usage with static ramdisks, with fast format, the RAM is still reserved, but the "System" process does not show it as long as the memory pages are not accessed. And that is why the creation will fail...
Very interesting but I am afraid that it will be difficult to reproduce. There is still something I would like to know. When you see these delays, what is the CPU usage of ramdyn.exe?
Cannot reproduce the issue. Please try to disable your antivirus, reinstall the software, and do again what you did previously.

The current limit before getting an issue is 33 characters that can be passed to format.com from the RamDyn command line. This is enough for what the GUI has to do with RamDyn. But if you are using RamDyn from command line with a lot of parameters for format.com, then yes, it can be a bit limited. I will set a limit to 99 characters.
