View Full Version : Issues with Detective Mode (massive FPS drop)

1st Feb 2010, 20:02
I'm having a VERY wierd issue...

Game runs fine at 50-60 fps. However, if I turn on 'detective mode' I drop to under 10 fps. As soon as I turn detective mode off, framerate goes right back to normal levels within 2-3 seconds.

Any ideas what's causing this?

My system specs are:

Core2 Quad Extreme QX9300 2.5Ghz
ATI 4870 HD x2 in CrossfireX (1GB each card)
Win 7 Ultimate 64-bit

hmm, have you tried turning off graphical features one by one and seeing if it has any effect. I'd start with crossfire, (a single 4870 should handle the game no problem anyway)

how are you viewing your fps while in the game

Hes probably using fraps or xfire.

And @ tc. Id take deders advice on disabling crossfire and see if that fixes it.
I have the same video cards and having crossfire enabled causes alot of problems in most games ive tried. But seems to be fine with batman tho , for me.

It can be OS dependent, If I enable sli in xp then the game crashes, but it's fine in vista64, although it still runs slower than with it disabled
