I have a relatively old system and wish to install The Witcher 3 from Steam in my SSD drive in order to get load times down. However, my SSD (D:) has only 37GB total, and the game installation allegedly needs 38GB. I also heard that SSD's need about 10% free space in order to perform well.
So what I am willing to do is split the installation between my SSD and a larger SATA drive using symlinks. i.e.:
- Download and install the game in a Steam library in the SATA
- Copy most of the files to a Steam library in the SSD
- Make symlinks in the SSD pointing to some files in the SATA
- Edit the game's manifest file so Steam believes it is installed in the SSD (Boltclock's answer here)
So my questions are:
- Will this break some kind of Steam's or in-game checksums?
- What kind of files (or which specific files/folders if someone knows) are less frequently used and thus will have less impact on load times if i put them in the SATA drive?
- Do I have to keep some free space in the SSD for temporary files and the like?
Thanks in advance, and sorry if this is the wrong place to post it.
EDIT1: In this question, user Viper_Sb hints at something like this being possible, but it is not clear how.
EDIT2: Actually, the question mentioned in EDIT1 only deals with linking the whole game directory, not splitting it's parts.
