Nvidia portrait mode on a widescreen laggy?

[Blorton]

I've recently bought keyclone and have been rotating my dell 24" widescreen to portrait mode in order to have two sessions going. It works well from a functional standpoint, but I'm seeing fairly rough frame rates that carry over to desktop "tiling" even when no games sessions are running. I've experimented with the fps settings in keyclone without success.

The os is 32-bit XP with an AMD XP64 x2 4800(socket 939) with 2Gigs of ram and an 8800gts with 320Megs. A single full screen Wow runs smooth as silk in landscape mode, even in cities.

I've not tried setting processor affinity yet - just ran across that one this morning. I have monitored system load with both sessions going and it appears I'm not pegging the cpu. (I do get freezes in the first session when I'm logging the second one in - that indicate anything special?)

Any suggestions? I'm planning a big system refresh in a few months, but have to spend money on other things first.

Thanks,
Blorton

if you have your monitor in portrait in XP that means you are running in dual view and not horizontal span.
It's a well known bug Horizontal Span vs Dual View on nvidia

I play exclusively in portrait mode and see no lag (anymore, it used to be totally unplayable).

But I only run one WoW at once per computer.

This may be rectified by downgrading to Vista.... but can't say for sure.

Can you even rotate AND horizontal span?

Ahhh, thanks for the pointer. I was somehow thinking still being on a single screen made it all okay - but now I "get" that I've put the nvidia driver in crippled mode.

I did try setting cpu affinity last night - was terrible.

Guess I'll take a page from Zin's book and split the second session off to another machine. I've been using a basic laptop with a 64meg nvidia 5200 in it for playing on the road, guess I'll go ahead and get keyclone on it as well and simply use it next to the main system.

Thanks,

AFAIK you cannot run portrait on 1 and landscape on the other in horizontal span, at least on the 8800gtx with current drivers. It might work if both monitors were in portrait. Works great in Vista though, (has to because of Aero)


Edit: :whistling: holy crap did I misread the original post. I thought you were using two monitors and the 24 was flipped for character #2 and #3.

You should be fine with that hardware and only two clients assuming you dont have all the video settings on max. I've not used just a single monitor for so long, that i'm not sure if there are any issues with portrait mode and directx or not. I would suggest running it in landscape mode 2x 800x1200 and see what your framerates are like that way. Not that you would ever play this way, but that would tell you if it's portrait mode that's causing your issues.
