(MY) WIN7 RC Performance review

Hey all hope u are fine

Well i downloaded WIN 7 RC x64 and i decided to post my idea and benchmarks for it,but as some of you may know,when i first installed it,it gave me a horrible performance in gaming and here is the link that how much problems i had with it but i decided to do a clean install and deleted the files that i thought they were the reason for this bad performance and now all i can say is WOW

Before i post the benchmarks let me talk about the OS itself.

First of all the installation was pretty easy and faster than both XP and VISTA 64 SP1.
Also the boot surprised me alot,it booted faster than both VISTA and XP which is great.

So lets get to the benchmarks

PC Specs:
Intel Core2Quad Q6600@ 3.4
Sapphire HD 4870X2
OCZ 4GB DDR2 800 RAM with 4-4-4-15 timings
ASUS MAXIMUS FORMULA X38 Motherboard
SEAGATE 500GB 7200 RPM HDD(With 32MB cache)
LG W2452V Monitor with 1920x1200 resolution
Catalyst version : 9.5(For WIN 7 RC X64) and 9.4(For VISTA ULTIMATE SP1 X64)

"ALL OF THIS PICTURES ARE TAKEN WHEN PLAYING IN WINDOWS 7"


3D MARK 06 (1280x1024 resolution)
Windows XP 32: 19500
Windows 7 RC X64: 19240
VISTA ULTIMATE SP1 X64: 18900


Crysis

Note: I use 2 great configs for Crysis and Crysis warhead which are CCC 2.1 (For crysis) and CCC 3.0(For warhead) which gives the game a more realistic look and will increase your FPS too

W7 RC x64 settings:
I used the latest Patch (1.2.1) for this game+ I ran it in 32bit mode.
Game settings used:CCC Level 5 + 0xAA
Resolution: 1920x1080
Map tested: "Island"

VISTA Ultimate SP1 X64 settings:
I used the Patch 1.2 for this game but i ran it in 64bit mode.
Game settings ued: CCC Level 5 + 0xAA
Resolution:1920x1080
Map tested: "Island"

All i can say is WOW really,i never played Crysis as smooth as i played it on Win7 i got about 2-8 more FPS than VISTA (depending on the scene) and it was really awesome,i enjoyed playing it






Crysis Warhead

Windows 7 RC x64 settings:
No patches used
Game settings:CCC Level4+ (Warhead doesnt have Level 5 )
Resolution:1920x1080
Map tested: "Ambush"



Windows VISTA Ultimate SP1 X64 settings:
No patches used.
Game settings:CCC Level 4+
Resolution: 1920x1080
Map tested: "Ambush"

Like Crysis i got about 2-8 FPS more in Windows 7,i've chosen a scene in this level and i always test it when i want to see how much my FPS has improved(Its exactly from the second game save to where some jets come and drop bombs)
As an example,my minimum FPS in this scen was 21 with Windows VISTA but it was 29 with Windows 7,pretty much like Crysis this game ran smoother and i enjoyed playing this one too





STALKER CLEAR SKY

Settings used in both OS:
I used the 1.5.0.7 patch for testing
Render:Full enhanced dynamic lightning (DX 10)
Quality:Maximum
0xAA
DX10.1
I used 2 great mods for thie game too: One is "Better depth of field" and the other one is "God rays"



My FPS was nearly the same in both OS,i got about 2 FPS more in Windows 7 RC.

FarCry2:
I didn't play the game i just ran the benchmark tool with this settings(Same for both OS)
Resolution: 1920x1200
Ultra high quality
DX10

Now this one is a little different compared to other games tested,i "LOST" exactly 2 FPS in Windows 7 compared to VISTA,but as i said its just the benchmark tool i didn't test the game play.

Windows 7 RC X64:
Average:59.98
Maximum:92.46
Minimum:39.91

Windows VISTA Ultimate SP1 X64:
Average: 61.71 FPS
Maximum:94.77 FPS
Minimum:41.36 FPS

Conclusion:
In the games that i tested(With the exception of FarCry 2 which i only used the bechmark tool)i was really happy with the way it performed,my main FPS increase was in "Minimum FPS" which is great and allows to have a better and smoother gameplay.
Overall i am pretty happy with this OS,and i will buy the final version defenitely.

So i hoped you guys/girls liked this review

No problem glad u liked it

Good job Maziar. Nice review, and its what we should all be looking towards, with DX11 to top it all off.
@ mmonkey, good question. Is the Gddr being used , or being used twice, like the older system, great question. I havnt tried W7 yet

Ive heard about this before. If I refind it, Ill post back. Not sure there was a solution tho, as I think it was mentioned in a different thread concerning a different topic altogether, hope I find it, and theres a solution

Thanks for the review Maziar. It looks like i'll be getting Windows7 as long as they're not charging too much for it, some of the pricing rumors have me a bit worried.

Unless those are 32 bit apps, where itll limit it under 4gigs, like xp

Sorry it's taken me a bit to respond, been away doing stuff. I cannot seem to get your piccy link to work, it just takes me to the XS. home page. When I get a chance later I'll fire up the W7 HDD and take a screenie.

Good news indeed. ATI driver is working on Windows 7

In control panel system page it shows 4GB

Does this memory issue bring you any performance hit ?

This is the page that makes me want to ask for my money back.

Lovely pic, if only it were real.

lol.... BG...

Yeah it works now thanks
Thats strange for me it shows 4GB and doesnt say 3.2GB usable,hmm

It was due to the awesomeness of the 8400GS that I was using at the time.
