I don't know whether you're familiar with JF-AMD, but just to be clear he's the AMD representative on those forums.

JF-AMD says a lot of things...

The newer version of Driver Sweeper its pretty good. It doesn't give me the problems with older versions. So I use it now with combination of TwL cleaning procedure and batch file.

In case it's not in this thread yet (cba to go through all of the pages), 7's sluggishness (esp. the mouse) has been solved for me by disabling "core parking":

Thanks to post this in, I'll add it to OP for sure!

Updates:

Disable Intel Hyperthreading
This is a controversial tweak with some conflicting results. Keeping Hyperthreading enabled and disabling Core Parking / optimizing Power Management (see Windows section below) is probably a lot more beneficial.

Check your LCD monitor (physical) settings for best pixel response times, ensure you have a good overdrive technology

Enabling AMD LCD Overdrive can reduce input lag on certain LCD panels
(Even if preview image fail to load, you can still enable overdrive, just click cancel for preview)

Problem is, it can often try to trick the pixel for too long, introducing noise and discoloration into your picture.

Most modern monitors already have this built into their controller hardware.

This is really only a benefit if you have a naturally slow panel. I personally don't use or like it."

Disable Core Parking Windows 7 Tweak may improve performance
You can show those hidden processor performance settings in your Control Panel\System and Security\Power Options\Edit Plan Settings\Advanced Power Options this way:

• First if you applied above registry edit already, set the ValueMax again to it original value: 00000064, this is REQUIRED for the current solution to work.
• Now re-open regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00
• Export a copy of this selected branch as safeguard
• Navigate the subkeys, switch the "Attribute" value from 1 to 0 for every subkey you want to appear in Advanced Power Options.
• The key ones you probably want to view there are:
• 0cc5b647-c1df-4637-891a-dec35c318583 "Processor performance core parking min cores" SET IT TO 100% so no cores will park.
• 3b04d4fd-1cc7-4f23-ab1c-d1337819c4bb "Allow Throttle States" Off

Processor Power Management in Windows 7 and Windows Server 2008 R2 docx should be read before finicking too much with those hidden settings. Additional infos.
I uploaded for you guys the latest pwrtest.exe from Windows Driver Kit Version 7.1.0 so you can check your own cpu spec with the command "pwrtest /info:all": Multiupload.com - upload your files to multiple file hosting sites!
A last warning: don't disable Processor Idle, this will only increase your cpu temperature, wear & tear and energy bill without performance gain.

If you look into Performance Monitor (Start Menu> Search), you'll see some IPv6 interfaces hooked to your real running network adapter(s).
Disable IPv6 tunnel adapter & interfaces

By the way, if Performance Monitor report you some performance counters are disabled, open a Command Prompt (Start Menu> Run> type "cmd" or Start Menu> Search type "cmd"), type "lodctr /r" to refresh/re-enable them all.

Disable unused network adapters and IPv6 related interfaces in Device Manager, tick "Show hidden device" in Device Manager View tab to show them all
Disable all ISATAP, 6to4 and Teredo Tunneling interfaces

I reached the 40000 characters post limit, so I'll start a separated thread for BF:BC2 specific tweaks

great thread...i've done more than half of these tweaks...and i feel my strong pc even smoother...that's an answer for ignorant people who believe tweaking pc is not a good fact and a must solution...thanks von, for your time posting these...

I reinstall OS on C (format it) but left disk D. Than I just delete folder of games.
Does disk drive D get fragmented this way when deleting games folder and leaving files that I need?
Will this way OS remove all registry of games I deleted ?

[TruMutton_200Hz]

^ Fragmentation is caused potentially, by adding new files after having deleted unwanted files on the same partition. Ohter potential causes are: increasing the size of existing files after having added new files on the same partition, adding new files after having decreased the size of existing files on the same partition, and adding new files / increasing the size of existing files on the same partition "simultaneously more than once".

The Windows registry is a file. If you format a partition, all files are deleted from it so yes, the old registry and everything stored inside it is gone.

I have 2 HDD's. One for games and the other for Windows. I setup UD3 for windows in Auto mode and in options I tick Put directories close to MFT, FragProtect, slider to Fast.

With my Gaming HDD I use Consolidate and in options I tick Respect high, MFT, FragProtect.
Then I went to tools settings select my gaming HDD and in High Performance I select Custom and I select the folders I want for high performance. For example games that are demanding on streaming from HDD.

Check out the first stickied thread at top of page...http://forums.guru3d.com/forumdisplay.php?f=27

i've always had HPET enabled since the early Nforce 4 days and never had any DPC, performance or reliability problems, DPC generelly hovered endlessly between 10 and 80 without any spikes when watching movies, playing games etc.

also without Hpet games don't feel as smooth i get some sort of pauses and in Resident Evil 5 i lost 7fps (regained by enabling HPET), movies also seemed to stutter more (High Definition movies).

but then again this is on my rigs, so your results may vary, no harm disabling Hpet, worth a try when troubleshooting but generally its recommended to leave it ON if you're using Vista / W7 (XP will show "high precision event" under device manager but won't use it).

also some mobos allow you to set HPET to 32bit or 64bit, set it according to your OS.

[harkinsteven]

Heres a tweak I find makes your PC very smooth.

Luafv.sys

If you have choose to permanently disable UAC and you are in the mood for an advanced tweak:

Based on my understanding and in simple terms, UAC uses a driver called the UAC File Virtualization Filter Driver or luafv.sys to trick legacy apps (apps that aren't correctly written for UAC's least privilege) into thinking they are running with the privileges they think they need but really don't. Of course, if you aren't using UAC then you do not need this driver loaded.

The setting is located in the registry:

This is they key in it's default (enabled)

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\luafv]
"Start"=dword:00000002

This is the key disabled:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\luafv]
"Start"=dword:00000004

What is the best setting for page file on Win XP sp3?
I now have set on C drive
MIN= 1536 (1.5*1024)
MAX:3072 (3*1024).

Should I set
MIN=MAX=1536
or
MIN=MAX=1024
or
MIN=512, MAX= 1024 ?

Which is for best performance?
Is it crucial to have set page file on partition where is XP ?

[Mr.Bigtime]

and According to RIFT developer they posted this at their forums

- Flash
Any programs which use flash (for example a browser playing YouTube) can incur a significant framerate hit in game. The reason for this is if flash hardware acceleration is enabled, it will cause certain video cards to downclock to 400 MHz, resulting in much lower in game framerate. This will apply as long as the flash application is open, regardless if it has focus, the video is paused, etc.
To fix this issue, either close any programs which are running flash, or change flash to disable hardware acceleration (when mousing over flash application: right click...settings...uncheck "Enable Hardware Acceleration").

"Always select 2/2.1 Speakers for your headphones if you want full dynamic range."

Does this statement refer to the Windows settings, Sound Card settings (i.e. Xonar Audio Center) or both?

Also, has anyone confirmed the validity of this statement? Do you really get more dynamic range with headphones by using the 2/2.1 Speaker setting? Where is the original source of this information?

Personally, I'm using Windows XP and I don't see an option for 2/2.1 Speakers in my "Advanced Audio Properties". The closest setting I have to that is "Desktop stereo speakers" and I'm hard pressed to hear any difference in sound after choosing it. My Xonar Audio Center does have a 2-channel speaker setting but it disables my onboard headphone amp so that's not an option.

Bumping since I might have another tweak:

Alot of those network tweaks have no effect what so ever on games such as fast paced shooters because they're TCP tweaks. Though the MTU (Maximum Transmission Unit), seems to affect UDP as well.

For those (easily seen in source OB engine based games by using net_graph in console), who experience loss or choke on their connection, lowering the MTU might help.

A smaller MTU will cause it to send more packages, but smaller. The downside is that your ping might go up slightly (30 ping might become 35 when lowering it alot). The benefit is that there's less chance the smaller packages will be fragmented and thus lost.

You sure about that last part..afaik a larger MTU helps prevent fragmented packets because more data can be sent in one packet.....router and NIC mtu's need to be same size fwiw..

I think a too large MTU can cuz packet loss also, tho I can't remember why...

You can try.....I did but not sure if it was really disabled. Check with DPS Latency Checker to know for sure.
