Good question. I honestly do not know (at this point).
Now with 64 GB of RAM, RAM is not the issue. I have never seen the FS2024 process go above 32 GB … and my system is equipped with 128 GB.
Regarding the RC size we find ourselves between “a rock and a hard place”.
- 16 GB is too small (= big LRU problem) … but at least it keeps the index small.
- 256 GB “solves” the LRU problem … but the large index will cause “stutters”.
As it seems even a heavily used 16 GB cache may trigger more stutters than a clean new 16 GB cache (I have seen people with such observations).
In the very first post of this thread I try to maintain a form of high level summary.
There I posted:
- Sizes above 250 GB might be a waste of storage,
- … as the sim might not be able to use it all (due to the nature of the RC index structure).
I think I will now have to add something like
- Sizes above 100 GB may impact overall performances (e.g. more stutters etc.)
In the end it will depend on the kind of flights that individual pilots prefer to make. As a sightseeing goose I take very long flights at low altitudes … so I will try to stick with larger RC sizes … because I do “prefer” stutters over waiting 10 to 30 minutes for the sim to finish launching.
I am sorry that I can not really give a good answer.
