Does anyone know what OpenGL version the game is running on?... would like to find out so I'm not guessing on the nHancer settings. Thanks.

Good question. I wonder how we find out?

To be able to select Perfect Landscape you need to run in a 32 bit color mode.

You need to run under OpenGL
set HardwareShaders=1 in conf.ini

"Attempt Stencil Buffer" must be selected
If you meet all these conditions Perfect Landscape should no longer be grayed out.

No Perfect with 169.21 drivers!!

This game was made using the OpenGL 2.0 standard but is 1.1 compliant. The current OpenGL standard is 3.2.
All versions of OpenGL are supposed to be backwards compatible, but I've had trouple with the newest Drivers from Nvidia so I've stayed with 186.65. So far I've had no problems.

Hi,

if anyone is having problems with 'tearing in screen' ie when you move pilot head with trk ir or mouse please try the following simple trick.

obviosly make sure your game is on open GL & not direct X

Vsynk is On in nvidia control panel

AND this is the one that got me, put screen refresh to 60 hertz.

I don't know why but the refresh rate helps a lot. I upgraded from a 7900 to a 8800.

7900 never gave me issues, last week upgraded & the 8800 was giving me issues??? found no solution until i changed the screen refresh from 75hertz down to 60 hertz.

that fixed it, haven't got a clue why, i thought higher was better.......anyone kinows enough to find a reasoning?

hope it helps with your post :roll:

Highlighting of quote mine.

I tried updating to newest drivers from NVidia after installing a new 8400 series card, had problems. Rolled back to the same 186.65. Still had some problems, tried changing refresh rate, no joy. A friend layed a 7900 series on me. Installed card, newest drivers, not happy with results. Rolled back to 186.65 driver, set refresh rate a 60Hz, and now I'm a happy camper. It seem that sometimes a newer, bigger, better graphics card is not always better. I am really happy with the 7900 series card. Maybe it depends on the system, i.e. processor, memory, buss speed, (age of computer), etc. When I have more time, I will probably look into it. Right now, I am happy that it works and looks great. I can run in perfect mode, the only time I get stuttering is if there is a massive amount of objects and there are explosions/AA. Even then it is not so bad that I get a complete freeze and miss a shot. I also run a gaming program in the background that turns off all background programs, keeps the memory cleaned out and assigns IL2 to one processor (dual processor).

Anyway to stay on topic. Thanks for the info on which version of OpenGL IL2 is running on. I have wondered that.

Take care,
C2

The reason is simple. You were running your monitor at a refresh rate higher than recommended for the video card/monitor combination. Vsync syncronizes the refresh rate of the card to that of the monitor. You get verticle tearing when the card tries to update the video date faster than the monitor can resond. Almost all LCD monitors will max out at 60hz (60 Frames per second). If you try to go above this, the monitor can't refresh fast enough. It will look o.k. with Vsync turned off as long as you are looking straight ahead, but when you turn your head quickly or snap view, you get the tearing.

Bottom line: The human eye can't register anything above 32fps anyway so leave your Vsync turned on. ESPECIALLY if you are using a Track Ir.
