Refresh rate goes to 60 when playing Doom3

Archived from groups: comp.sys.ibm.pc.games.action (More info?)

My desktop refresh rate is 85Hz @ 1024x768. When I play Doom3 @ 800x600, my
refresh rate goes to 60Hz. I don't know if this is what's causing the neon
green imp fireballs, but is there a fix for this?

As the other poster mentioned, the video card should contain refresh rate
overrides that force the refresh rate to specific values. For some strange
reason, OpenGL applications normally set the refresh to 60Hz.

Alternativly, you could try running the game in Windowed mode.

If the fireballs aren't supposed to look neon green, than that's a
different issue. In this case, you might want to look for an upgraded
driver.

You can also create an autoexec.cfg in your base directory containing the
line "r_displayrefresh xx" where xx is the refresh rate you want (I use 85).
It won't help for other OpenGL games but it's a quick fix for Doom3.

As mentioned already, many games have the ability to set the refresh
rate. However, many do not. The problem is that Windows XP defaults to
60 when changing resolution, switching to DirectX from your 2D
desktop, etc.

Windows 9x actually allowed you to change those defaults, but XP does
not, natively. There is a simple utility called REFORCE.EXE that will
change the default refresh rates for you, fixing this issue
completely. The utility is free.

NVIDIA drivers allow _different_ forced-refresh settings for _all_ allowable
resolutions; ATI drivers allow forced refresh settings also, both thru the
display properties. I think you'll find that whatever forced rate is set
thru the display properties will also show up in the dxdiag utility. It's
that way with the ATI drivers.
