Terrain "shimemring/flickering"
« on: January 30, 2008, 01:06:41 PM »
Just built a new rig with a GF 7600GT 256 m card. I'm running hires textures with 1280 x 1024 screen resolution.  I'm noticing a bit of flickering in and around airfields and trees. Anyway to tone that down?

btw...I'm getting 75 fps with that card + a Intel Core 2 Duo 3.0 cpu. Nothing wrong with 75 fps but shouldn't that # be higher?

Thanks

If you have Vsync on and screen refresh rate at 75Hz, than this is normal.

If you want to have higher frame rates, turn Vsync off. If you don't experience  tearing, leave it off, otherwise turn it back on.

Without seeing a screenshot, it sounds like a Z-bias issue on the shimmering.  Which driver did you use?

And 75FPS is the monitor refresh rate, so it sounds like things are running well.

Low number of FPS =  Slide show = bad
High number =  seamless, smooth pictures.

Max, if you are using the latest nvidia drivers, they are more than likely the culprit. I recently changed to the latest 16x.xx driver, and started getting the issue around a lot of trees. This does seem to be only on that newest big map i think. forget what it is called.

I have a 7600GT at the office.  I'll check to see what driver I have installed.

I couldn't find any driver info in the Nvidia tab of the display CP. Whatever shipped with the Abit mobo driver CD is what I've got. Should I download and install an Nvid driver? Which one, if so?  What does one do about Z-bias?

Yesterday I flew a couple of sorties with vsynch off. My frame rate jumped way up (80's - 120's) and the shimmering _almost_ went away. Someone on 200 warned that vsynch OFF has detrimental gunnery consequences. Boy...were they right. I saddled up d250 behind an NME and opened up with Hispanos + 50 cal...NOTHING. I logged and turned V-S back on. I'll live with the shimmering :D

There are a couple of objects in the game which do have somne Z fighting happening and will be corrected in the next patch.

Playing the game with vsync off is not a good idea.  It can have detrimental effects on many aspects of the game.
