View Full Version : Help! From 35fps to 11fps in Vista, when I turn on AA x2

I've just installed IL-2 Sturmovik 1946 in Vista. I'm getting 35fps before applying any antialiasing settings from the nvidia control panel. If I choose to override or enhance the antialiasing to a value of x2, the frame rate drops to 11fps.

I have made no modifications to the conf.ini file and am running 1946 in OpenGL with a resolution of 1024*960. I have also installed the AMD Dual Core Optimizer. I installed the latest patch (4.08) but this made no difference. I have the latest NVidia drivers (September 2007) and the latest sound drivers.

My setup is: AMD X2 64 Dual Core 4800, 2GB RAM, 8800GTS 640 MB.

I'm surprised at this! I would have expected much higher frame rates. All other software/games run fine (e.g. World in Conflict, FSX, Oblivion, etc etc).

Can anyone help me? http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Regards,

Mark.

Not sure about that Mark...

But here's my attempt:
- I am running E6600 Core2Duo, 8800GTS 320MB
- Running on XP, have tried on Vista (available via dual boot), FPS are lower, but not too much....
- NVdia's Control Panel: AF ='Application Controlled', AA=16Q, Extension Limit=Off, Threaded Optimization=Off (Just mentioning the settings related most to performance - I think http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif)

My OpenGL section of conf.ini, you may try and use Copy/Paste in to your conf.ini, make a backup copy of it first though... http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

thanks! i'll give this a whirl tonight. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

I'm dual-boot too, so if all else fails, i'll fall back to XP.

A big thanks to FoolTrottel for your post! Cheers!

I copied in your conf.ini settings and changed nvidia control panel to reflect your settings and the game went back to a very playable 35fps from 10fps. Result!

Thank you. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
