Hello all!

I've read messages about using a lot of memory in kX mixer for skins. Yes, this is about 15MB in 3532

But why not to unload the pictures when mixer is minimized in system tray? It will take a lot less memory.
Reloading of jpegs won't take a big time and the memory will be saved

Eugene Gavrilov

well, the files are extracted from the 'rar' archive first [this takes time]
so, it might make the mixer much slower

there are no problems with freeing kX Mixer picture cache on window close
probably, there will be an option (for fast and slow machines)

--

anyway, I've managed to decrease memory usage by 4Mb (there was a bug in 353x series) -- it should take less now -- this fix seems to be included in 3533rc1

I think there's a good idea to cache 'em on disk in unrared format e.g. in TEMP folder after starting kX mixer and delete on exit (like winamp does with zipped skins).

Is 3533 released? I cannot find any information about it on kX project site

Eugene Gavrilov

the 'general discussion' -- it was released unofficially for testing purposes

just unrar the skin and rerar it,using the min compress radio,then the memory usage can down a lot

1. Only UNRAR part of RAR archiver is FREE, RAR costs some funds, so it is not possible to include RAR compression code into a free project
2. As I think, memory used not by UnRAR library, it's used by jpegs, and it's better to unload them on minimize
3. Simplest way - uncompress the skin into a 'temp' directory and use it as a cache.

What do you think about this, Eugene?

Eugene Gavrilov

perhaps using a temp folder might improve memory issues
I'll think about it (well, the actual idea isn't 100% new, however, I didn't want to implement it due to lack of time because there were not so many complains on memory usage)

In addition, a big amount of memory is used by debug MFC dlls
Is there a way to build executable using retail DLLs (EXE: debug, DLLs: retail)?

Eugene Gavrilov

there's a way
but 'retail' versions of MFC libraries don't wish to work correctly (lot's of strange bugs / failures)

we are currently migrating away to our own GUI library which won't be MFC-based
most of the code is already re-written
as soon as this process is finished, the new builds will need only msvcrt.dll ('release' build)

i am serious,i test it with the creation3 skins,with max compress radio,it will take up to 33mb memory;but if use min compress radio,the mixer only use 6mb memory

if you think jpeg is the problem,then convert them to bmp and remane them to bmp,ihave also tested it,it can work correctly

but when skins will be cached into a temp folder without compression - probably will be 3 MB or less

Windows cannot display JPEGs in their native compressed format and cannot uncompress they directly in video memory, using system ram instead, so it's idea to convert skins in BMP, unrar them once to disk and enjoy
