Homebrew DS Doom slowdowns?

[Kestol]

Oi people...
I just tryed DS Doom that i got from this official site: http://www.dsdoom.com/

But can this be correct? that the game runs slow at times...
I was really expecting steady 60 FPS but already at the begginning it's running a bit slow

Beginning is here:

Anyone can help?

I'll take a wild guess here... maybe it's because your card got too fragemented over time ? Try backing up your card, formating it, copying it back, after that retry.

Try defragmenting your card.

So the game should have any slowdowns?
If i understand correctly?

I thought you aren't supposed to defrag TF media, just format it?

Just formatted it.. But still slowdowns occur...
I tryed installing doom 2 and it slows down at the moment i enter the big room whit the window to look outside and the dude firing at me from above.. I can get him down by pressing a button (first level)
