Windows 7 RC1 MBxing performing worse than on Windows 7 Beta

I have been MBxing for around 2 months on one PC. The system setup is an AMD 64bit dual core, with 8GB ram, 1 x Nvidia 9800gt Graphics card, and 2 raid 0 drives.



i mutibox using innerspace, using 2 screens.



Initially I was using windows 7 Beta, and everything worked really well, I did not get the FPS that many seem to have but I did have 25+ consistantly which is very playable. All other aspects were very smooth.

Yesterday I did a clean install of Windows RC1, The install was even easier that the beta as the install recognised the raid drivers without needing third party input. The install shows no conflicts or errors, Windows 7 performace thingy gives a rating of 5.9, withthe processor and graphics individually ratting 7.1 and 6.9

I have have set up wow in he same way as before - no changes.

I am now seeing a significant reduction in video performance and have significant sound distortion, where i had no probrlems under the beta.


I would be interested in knowing if anyone else has experienced any issues, and advice on where I can look to resolve sound and performance issues as W7 is a glorified Vista.

thx in advance.

Have you tried to update your video drivers to manufacturers drivers instead of the included?

for me the same between beta and rc.
juste less log files to deasble on the rc

I am running Win 7 RC, and for me the performance is superb. If you didn't update video drivers like Zanthor mentioned, make sure to do that. The ones that come with Win 7 RC may BSOD you ;) Of course, I've had the newest NVIDIA drivers cutting out on me and giving the "driver stopped but recovered" thing during play, maybe 3-4 times over the last week. That's about the only issue I've had.

Graphic drivers from nvidia have been checked - they are showing as the latest.

Any thougths ont he sound issue -Significant distortion when sound comes from all 5 instances.

On Windows Update? Or did you go to nvidia.com and download version 185.85? (or use their update widget thing)

Also, make sure you disable Aero.

The thing that matters most in the WoW config is your multisampling setting, in the resolution tab of the video options. If that's not set at a 1x multisampling setting, you're going to get a significant performance hit. So I'd maybe double check that, since it's not usually the most obvious thing in the wow video options.

As far as sound from all 5 instances, that sounds like you have "Make game believe it is foreground window" checked in ISBoxer -- I'd uncheck that.

Thx Lax

The driver is from Nvidia.

I am being a noob, how do ou disable aero?

checking the other settings.

Control Panel under Appearance and Personalization, select "Change the theme" and select Windows Classic. This will disable Aero and give you a high performance no-frills Windows theme much like Windows XP.

But aero is so shiny! lol Plus the sidebar is nice to monitor CPU/RAM usage and I have an add on for it to monitor my WoW server status lol

I had never used the 'beta' version of W7 so I cannot comment on that. I did however upgrade from Vista Ultimate x64 to W7 RC1 and everything is so much smoother. I even keep Aero enabled while 5 boxing on this one computer. I have an Intel C2D e8400 and an nVidia 260 GTX [216 Core] and I can stay above 50 FPS on the window I have focus on [Azeroth/Outland]. I was doing some searching a little less than a month ago and someone with WoW FPS problems [non-multibox related] had loaded the Vista video card drivers instead of the beta W7 drivers and it fixed his problem. I tried that myself but saw no changes what-so-ever on my end. I don't think the Vista drivers use the WDDM like the W7 drivers do though, which is supposed to be superior.
