Poor performance with HL2, Win7-64bit
Hello,

I've been searhing high and low for anyone with a similar problem but can find no-one. I have the following hardware:

CPU: AMD Phemon II X4 955
MB: Asus M4N82 nForce 980a
GPU: BFG GeForce GTX 275
RAM: 4G PC2-8500C5

Running Windows 7-64bit with 191.07 Geforce and 3d vision drivers.

When I play HL2 in 2d, it runs ridiculously well but when I switch to 3d it runs really awfully. It's just about playable but it's not good. Not sure how to measure but it looks like way less than half the framerate. Even with graphics settings down at minimum, it's exactly the same. I have the HDR/Bloom set to "none" as recommended. Not sure what else I can try.

Does anyone have any ideas or a similar problem?

Could you specify fps number concretely?
Use for example fraps and play with and without stereo, make graph and post it here.

Notice that there is forced vsync if 3d vision is activated so you can never have more than 60fps in stereo, 120fps in non stereo respectively.

Hi,

Thanks for the help. I've tried this with fraps, playing for about a minute without stereo (left graph) and with stereo (right graph) around the same bit in the game: Just near the start when you have to pick up the can and place it into the bin then you walk through a big hallway and go outside. It's when I get outside that it really starts to suck. As you can see, without stereo it's pretty much constantly at 100FPS, which is what my monitor's refresh rate is, but it goes as low as 15 in stereo :( It's definitely worse when I'm outside and there's lots of scene to render, or when there's lots of monsters and fires.

Thanks again.

It's probably the 3d laser sight. Try turning it off.

You're right, it is that. Thankyou very much.

I wish Andrew could give us a little help as to why the 3D laser sight makes many Source games slow as hell, or at least if they plan to look into it in the future =/

It sucks so much having to choose between good performance or a 3D laser sight in some of my favorite games because of something that hasn't been addressed yet...

I haven't seen him posting in a while. Maybe he is taking a holiday break to get ready for Fermi.

His last post in the 3d vision section was on August 11th (I didn't check other sections as it wasn't relevant).

So, he has been gone for a couple of months or alternatively just lurking without being logged in.

Good riddance, his mallarky on " I'll look into this issue ", with no mention of it ever again was getting tiring.
