*Holds hands up* I had a dodgy download. From 25 FPS earlier,it is now excellent (50 plus)
Ok, did a complete reinstall (year zero) wiping out all traces of CoD from system (registry the lot). I would recommend trying this if you are having serious problems too, and nothing else is working for you.
Can confirm the framerates are now superb, performance is generally good barring slight microstutters at low level. Still not a fan of new landscape and different pits look (though the reflections are now back after my corrupt download and complete reinstall).
Overall, fairly happy thus far. Have yet to test new Spit prop addition. I apologise for playing funny buggers and being a sarcastic gimp prior, lol (have removed the post).
My performance was horrific prior to the complete reinstall though, in mitigation. Also remember (very important) to check that 'Stereomode' for 3d in confi.ini has not reset itself (it does) with a long string of numbers (6 figures or so I think beginning with '3') and keep it to 0 (your 1c SoftClub folder, not the other).
Much better now. Yours penitently, Orville.
Cheers.
