I have 128GB ram on my system and Icarus was using 124GB of it. Might want to look into that devs!External link →
DLSS is currently causing a major memory leak. There might be others, but that's the main culprit. We have informed NVidia (as its in their DLL). It's in the public DLL, so it doesn't just affect Icarus. However because we extensively use it, the impact is severe.
For now either reload regularly, or turn DLSS off, are the only workarounds. We hope to have that fixed ASAP.
