I didn't read much of this thread, bit's and pieces. is about it. IMHO, the nv 275.35 (or33?) Drivers set is a
Great fairly recent, yet older for older games too. I run nv 295.73 now, as I waited awhile before I updated them.
I had had some issues with some games with the drivers I ran before the 275 version. I run the latest Physics drivers as well.
Also Precession CP I get from EvGa for fan control, overclocking etc. (I am a life long member of EvGa) which is not hard to do
just register one EvGa card you've bought there and you'll always get EvGa Precession Tool CP .
If your not running Railworks games anymore, then you need not worry about what driver to use, if you were, I'd
get the Legacy Drivers from NV that came out around the time RW's did.
As far as using driver sweeper or any application, to remove all parts/bots of a Driver, before installing your
pick of nv Drivers, I don't use any of them anymore, I've found through the years, just install the new drivers and that's it.
2dGuru I think stopped posting Driver Sweeper for just that reason, does more harm than good. Again just MHO, no more.
Doing it the way I do I never have issues anymore with drivers and games. Nvidia knows what they're doing, they will install
them correctly. In some cases maybe it is necessary, don't know. I just know by my experience with NV drivers is all.
The Newer drivers as you know give you a choice of what you want to install, "check boxes". Again I don't do a Custom install,
I install them where NV wants them to be. Some stuff you don't need to install, but I'd be real sure before I started un-checking
off BOXES
None of this means anything if you have to install special drivers for running 2-3 Monitors, as I have never ran but one
monitor at a time. Just more headaches if you ask me, just don;t know anything about anything but NV reference Drivers.
Also I would not install any third party Drivers, just NV Reference Drivers, and only those. I use EvGa Graphics cards but
I don't use EvGa Display Drivers, though I'm certain they are probably safe as I think they just use NV Reference Drivers anyway.
Don't know that any of this helps, merely sharing what I do, that works BEST for me.

Oh and if you really think you need
too use driver sweeper etc., instead use add remove, I think that would be much safer than Driver Sweeper and or any Driver
removal app out there. Best of Luck Hawk!!

Again, don't know anything about Multiple Display's Gamer Dude does.
I just know Basic Installation of nv drivers for one monitor and one GFX card.
BlueBoy that's a long ass post for me...LOL!! On a final note, running older game you may have to use your NVCP, use
Triple Buffering, instead of Anti Aliasing or Anatastrophic Filtering etc. As back in the day (old games) they didn't
use a lot of the new Technologies they do today.
