Suspend & wake up => loss of performance

[Martillo1]

Hello all, I have found out that putting the system to sleep (suspend) in Vista 64 and waking it up results in a loss of performance. I am talking about going from ~60 fps to ~25 fps in DCS Black Shark. I suspect it is something related to CPU, but I cannot assure.

 

System Specs:

• Vista 64 Home Premium
  
• i7 920
  
• Asus PT6 Deluxe V2 (Note: C-State Tech not specified/auto in Bios)
  
• Asus ENGTX260 (Nvidia)
  
• 6 GB RAM
  

No Overclocking.

 

Installed Asus applications:

• Gamer OSD
  
• SmartDoctor
  
• AI Suite
  
• EPU-6 Engine
  
• Turbo-V
  
• PcProbeII
  

Any idea? I prefer suspending the system and resuming it more than letting it on all day long, but not at the price of performace degradation. I do not want to start it up an shut it down two or three times a day either.

its the Windows its self.

 

best bet is do a restart.

So no solution for this? Do Windows 7 suffer from the same problem?

I never liked the suspend or sleep feature either... sometimes the PC would not even want to wake up so... I stopped using it. Why don't you just leave it idle and turn off the monitor only, idling it doesn't use as much power anyway, especially with latest CPU's that have power saving features like lowering CPU frequency etc.

You are right, except for the fans. Suspending "freezes" the PC and turns off the fans. In the long run they will last longer if they are stopped.

 

I suspect the problem is connected to the well known screensaver problem in Vista 64.

Does Vista have the hibernate feature that XP has?

No, it has not. I hope W7 is better thought.

Sure Vista still has hibernation...maybee you turned it off on accident?

Generally after woke-up the system there is a big chance that something didn't wake-up... My case is that after woking up system, my sound card doesn't work. Need to restart and that's all. That's why I don't use this feature :|

[Martillo1]

It has been solved misteriously. Maybe drivers... maybe M$ updates...

It happens sporadically, if you have different settings for energy-saving and hybernation in BIOS, graphics card drivers and MS-energy saving. Especially the later need to be set manually, at least for older driver versions.

 

IIRC there is already a thread about this.

I dont usually have that particular problem but Ive always had problems with sleep feature in every version of windows Ive used. Its a mixture of Windows and lousy firmware in the bios. I generally have stability problems or devices that dont get recognized after its woke up and even when my pc is asleep it wakes itself up all the time. I stopped using it. Fans are cheap and pc doesnt draw a lot of power when idle. I mainly was worried about my hard drive not getting any rest, but in reality Ive only had 2 hard drives fail in my life time and eventually Ill move to SSD so its not a big deal.

I'm using Vista 64 home premium and use suspend (sleep) all the time with no loss in performance in DCS or any other game. I do generally reboot after every 20-25 sleep cycles.
