After reading Jon's comments with regards of his GTS 320 and is problems with games under Vista, and in particular this post here http://www.nvnews.net/vbulletin/showthread.php?t=85918&page=4, decided to do a bit of an experience with some of the games I have installed at the moment under Vista

Test system

Windows Vista Ultimate 32 bit
System bellow. No OC on the 8800GTS 640 (I can't anyway :))
Processor at 2760 (230 x 12)
Max resolution of my monitor is 1280x1024
2 gigs of PC3200 ram (although for some reason on the compatibility mode only 1 gig of ram shows up)

I used FarCry Benchmark utility from Guru 3D/ Game patched to version 1.4

FarCry under Vista, no compatibility mode

A mighty fine difference as you can see
I will try CoH, and other games that I may have

If any of you guys out there has tried this, show us your results.

Interesting. So compatibility mode actually increased your fps? That seems a bit strange. Any explaination?

Ok, CoH

All in game options set to Max or Ultra. No post processing. AA enabled from in game

Compatibility mode on

Not much of a difference here. Will try Serious Sam

None. That's why my interest. CoH shows no gains, but i need to check with other games to see what the results may be.

(although the fog on Vista pure mode seems very odd looking though)

According to your first post, FarCry did show some performance gains under compatibility mode though, unless I misunderstood what you were saying?

Sorry, i should have made my answer clearer
No, i do not have a reasonable explanation why FarCry would run faster in compatibility mode than on Vista mode, hence the interest on this Benchmark and to see if more people have same gains under different games

Okay, I read that backwards- and now that I'm thinking about it I do not know why I read it the way I did. :o

I was thinking that the "compatibility mode" was actually the exact opposite of what it really is- you know, like reversing it I guess you could say.

Kinda' hard to describe what I was thinking- but I was waaaaaay off.

My bad. :o :(

I've got FRAPS installed now so I'll try a couple of games when I get home to see what difference it makes.

What I could really do with... does anyone know where I find that app which shows how much local/non local video memory a game is using? And does it work in Vista?
