At boot up, enter the BIOS setup. Usually this uses Del or F2 - there should be a prompt on the screen. Work through the menu. What you need is probably in the "Integrated Peripherals" section.

Whatever you have as Shared RAM for the videocard, double it and see what happens.

Notes:

1: This RAM will be unavailable for applications.
2: Do not, at this time, make any other changes. You're playing in a sensitive area and "mucking around" is not a sane option. If you inadvertently change something - or think you have - just quit without saving. There is the option to restore the defaults with, usually, F7.

Most motherboards, if rendered unbootable by insane settings, will, after a couple of unsuccessful boots, offer to reset the defaults. I'm NOT trying to scare you off, just advocating caution until you become familiar with these settings. Careful tinkering here can be very rewarding. This is where you can really optimise performance.

In the Advanced Chipset Setup section, I found the DVMT/Fixed Memory option set to 128MB. I changed it to "DVMT Mode", so that the graphics chip would "dynamically allocate system memory as graphics memory" (according to the blurb in the manual) but it didn't speed the game up at all

As a last attempt I'd try fixed at 256MB.

lolwhites · Post by **lolwhites** » Thu Feb 28, 2008 8:07 pm

The BIOS won't let me do that. It's 64, 128 or DVMT Mode

I'm afraid I'm out of ideas.

Sorry.

Go mad with the spondoolicks and buy yourself a kick ass graphics card...........that wasn't very helpful, sorry, just spent 6 hours on helplines trying to fix wifi problems..Waaaaaaaaaaaaah

I have the same problem, frame rate of 4 when launching, because I have the planet in view. Hitting arrrows keys a lot, I can turn around and the frame rate goes up to over 10.

Seems to be a common problem: (Try "oolite intel 945" on Google)

I would have loved to add the URL here, but not only did I have to jump through hoops (register) to add this hopefully useful information, but it seems I must wait a day to post an URL. Goddamn spammers.

BTW, glxgears reports over 900 FPS.

Unfortunately my numbers was not from fullscreen. But then this is only a Dell Inspiron 6400 (also called e1505) laptop with two Intel Core Duo T2080 (1.73 GHz) and this for graphics:

OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 945GM 20061017 x86/MMX/SSE2
OpenGL version string: 1.3 Mesa 7.0.3-rc2

It's the same numbers reported by someone (with CoreDuo T5500)
at the Berlios bug report "[ Bug #12619 ] Users accuse slow rendering with accelerated video".

What happens if you type:

glxinfo

in a shell window?

It really does sound like you're software rendering the image. I have here an old Hewlett-Paqard desktop machine (i.e. Compaq inherited - the machine's probably at least 5 years old) with Intel 845G graphics, i.e. the crummiest of crummy integrated chipsets, and get 14fps full screen facing the planet.

I have gathered that the 945 may actually be worse.
