Title: DoomAttack really really slow. Help!
Post by: dougal on November 08, 2011, 05:33:41 PM
I tried running DoomAttack from the CF drive. Tried running the 020 version @ PAL Loweres

The FPS is really really slooooooooooow as in like 2 FPS slow.

My A1200 has a 68030 @ 42Mhz and 4MB ram. (I have 8mb but set it to 4 so the PCMCIA works)

Is something wrong??

DoomAttack was fastest engine on 68020 and 030.
Much better on 68030.
i played DoomAttack when was released and on my 68030@50 Mhz i played with 13/14 fps with Doom for the first 3 episodes.
Ultimate episode was very slow on 030, i  finished the game with 68040.

2 fps is too slow..
i think you should play at 10-12 fps.

When i had only 4 MB of RAm, some games and demos are very slow, but with 8 MB..a great improve in speed.

It's probably the flash drive.  If it takes too long to fetch information from the .wad file it will wait for it to load until continuing.  Also, if it's loading code to the Chip RAM that will slow it down too.  If you have a real IDE hard drive sitting around or a RAM expander that will go up to 32 MiB or more, they will both help.

For the 32 MiB to help, just rename the .WAD file to something else, make a softlink from the Flash Drive to the RAM disk and copy the .WAD file to the RAM disk every time you start the game.  If you've done it right, you shouldn't need to access the Flash drive except for save games.

4MB of fastram is not too much to play doom. You should try configuring your card with 8MB as there are some levels that may not load at all.

Add buffers in chipram to make disk access faster. You can launch the system tool "NoFastMem", then call addbuffers command pointing to the volume where you have the game. e.g.:
addbuffers WORK: 300

then launch the tool "FastMemFirst" to reenable fastram and you can launch the game and it will load slightly faster.

Anyway if the game runs at 2fps with a slightly reduced screen it run slow, I have run ADoom on a blizzard1220 and it wasn´t so slow with low detail and a slightly reduced screen size. Do you have your cpu caches enabled? you can enable them with the cpu command. Maybe you have chosen a slow chunky2planar module?

my 030 playing DoomAttack (http://www.youtube.com/watch?v=mffCQHTiJwI)

It's still a little too slow on mine with music, if you disable the music it gets a little bit quicker so give that a go as well.   I think NTSC is the fastest screen mode to use BTW.

That's actually not too bad at all.

For comparison here's my 386DX40 with ET4000 VGA running Doom:

(sorry for terrible phone video but you get the idea lol)

I have to run in low detail with screen size down a couple of notches to get it smooth when music is enabled.

Just watched your video NovaCoder, and that's pretty impressive for an 030.

Dougal, I'm suprised doom works in 4meg, I seem to remember having to jumper my ram card to 8 Meg if I wanted to play doom (I was in the same situation with my PCMCIA).
Are you sure you have all cpu caches enabled?  Type cpu in a shell to find out.
If you're booting with no startup-sequence make sure you run setpatch first, then doom.
