General Questions
Performance
DynDOLOD is a set of tools that generates a LOD mod based on the load order and the options/settings made by the user. The visual results and the performance impact are what the user chooses it to be. Based on the settings and user choices, the resource requirements and performance impact can be less, same or more than the LOD of the vanilla game while the visual result is always vastly superior.
Certain INI settings can affect performance much worse then LOD ever could.
There are 3 presets: Low - almost none. Medium - like SkyFalls + SDO but 1000x better visuals. High - certainly yes. RTFM to adjust every detail yourself.
Virus?
Nexus automatically scans every upload. Look for the green/blue circle checkmark for each file on the files tab.
Check with https://www.virustotal.com to rule out false positives.
Older versions?
Older versions are outdated, gone and should not be used anymore. Wanting to use older versions for any reason means doing it wrong
If a third party tool or guide requires an older version, the tool or guide is outdated. Contact its author for help or a fix for the issues with the tools/guides.
Troubleshoot or research errors and fix their cause if possible. In case of questions, problems or bugs ask or report them to the official DynDOLOD support forum so issues can be solved or fixed.
