Now i had to buy a "new" gfx-card and got completely different results.

The NV-lasersight isn´t useable anymore - i get a huge speed-difference with or without lasersight.
By activating lasersight, fps drops down to 5 or less...

HDR is working - just that the change in brightness takes twice as in flat mode...

I switched from 6800 to 7950 - and it´s realy worse - in nearly all games i´ve the same 3d-speed as
with my 6800 (by disabling lasersight!!) - with lasersight, i get perhaps 10% of the 6800.

Within some games, it´s pure horror to swith in 3d now - the hit is rally trophy, flat mode >300 FPS ; 3d < 40

I´m close to switch back to 6800 - FPS isn´t the real problem, but i´ve the "lasersight-crash" in each game...
... it´s completely gone; unuseable


163.75/162.50 combo (which was close to be perfect on 6800)

If it makes you feel any better, I'm still running a 6800 GT on my XP rig and that thing still has some life.

you better dig up some old stuff... I bet you'll find similar problems from other users.
I think it was a 'problem' with the driver and the Games. Some games run good/better with newer driver, but a lot of games work much worse with the newer drivers. You could test the driver of my sig, if you play a little older games.
I think only Bioshok and maybe IL2 work better with the newer one...

good luck trying

Yeah, you might have better luck with the 91.31 drivers.

thx for tips - now i tried a lot of drivers from 9x.xx up to 169.xx - allways the same problem.
It seems, that 7950 isn´t made for lasersight...

HDR, AA, AF, vsync, stereotexture - tried all - no change
It´s a shame - the quality of the lasersight would be very well.

I´ve tested just hl* and crysis...
... perhaps it´s working within ogl.

Did you try disabling one of the cores? Maybe its an SLI issue?

I assumed it was the non SLI card = the improvement of 7900GT...

However my 7900GT or GTO or GS (I'm not shure after my replacement) works good with lasersight - I have it on in all games which need it:
- BF2
-Fear
- COD2 and 4
-CS
- Portal

It 'works' even for some other games like racing games, where it is useless
