Is D3D v-sync not enabled by default? What driver version? I'm using 7.76 with a Geforce 2 MX400 and I think D3D v-sync was on by default. I had to use PowerStrip (ver 3.9) to force it off. PowerStrip only shows the option to force disable it (not enable).

OpenGL v-sync should also work in any game that uses OpenGL, such as Half-Life. I have it enabled and don't get any screen tearing on my card in HL.

I think it might have been, or I believe it was with the DSD Override tool that comes with RivaTuner. I believe I’m using 45.23, which looks to be a recommended driver version.

I’ve not heard of or used PowerStrip before, even if you can’t force it with that, but I’ll have to check it out. Thanks.

Yeah, so I had to install the latest version of PowerStrip as the earliest one kept causing my monitor to lose connectivity with the GPU. I’ve enabled v-sync with OpenGL anyway, which RivaTuner has, too. Bit weird there’s no v-sync for Direct3D with PowerStrip. It’s enabled for both with RivaTuner, but it still doesn’t work. 😕

I would try different drivers and then try RivaTuner again.

I know 45.23 is often recommended, but there's no one-size-fits-all detonator driver, in my opinion. For instance, on my Ti 4200, full-screen DOS window in Win98 refuses to work with 45.23, but works fine with the slightly older 29.42.

45.23 came out over a year after the release of the Ti 4200, while 29.42 came out just a few months after. Generally, the longer after the release of the hardware, the more problematic the drivers get with detonator drivers. So, you could start by checking something like 29.42 or slightly later.

I think 45.23 is often recommended, because it is one of those releases that seem to generally work well. But it is far from ideal as far as it comes to performance with older hardware as it has significant overhead.

I personally use mostly drivers that were released when the hardware was still current.

Okay, thanks for the suggestions. I'll try tracking down some that are earlier and report back. 😀

Well, I grabbed what I thought was the correct 29.42 driver, but it claims I don't have an Nvidia card installed. For my system, I have to have all the config/ini files and to install it via Add New Hardware. The version I downloaded for Win9x is just an installer.

I'll try the one from Phil's Computer Lab...

EDIT: Nope. Same thing. Even if I try and install it via Device Manager and Add New Hardware. It just recognises it as a Standard VGA Adapter. 🙁

Still no luck with this. I've tried 29.42 and 30.82 and neither think my card is there. The 30.82 wizard says it's not found in the PCI ID under NVAML.INF, which lists the card. I even tried re-installing 45.23 so the card would be properly listed and then tried installing one of them, but unsurprisingly, if the latest is already on, that's what will be listed as being on. So far only 45.23 work for me.

Ah-haaa. That'll be why... It isn't just any old Geforce 4 Ti 4200. It's because it's a Geforce 4 Ti 4200 with AGP8x. So it looks like 31.40 is the earliest I can go back to.
