I request this for several mods.
The mod creators have lmited influence on the performance by the file formats. By using PCX and TGA for example. If the player enables the -jpgtga flag he is able to get better quality, if not he can save performance.
So now the problem is that most mods do not want to have many seperate VPs for low-end and high-end systems.
And now let's take a shockwave I just made for TBP as example.
I've a high-end version that looks sweet, and low-end version that looks, well, ok.
Both are EFFs (DDS).
How can we implement it in one download?
Now my idea:
The -highend flag chooses files from the "/data" subfolder "/highend" (or "-lowend") over the files in the "/data" folder. So each player can use the best setting for his system without copying or deleting anything.
This will make FSO more comfortable.
