Hi !
I recently installed avast 5 (free) on my computer and it’s working, that’s not my problem.
My main concern is that i use RivaTuner to switch profiles for my graphic card and i use it with the hardware acceleration monitoring.
Thing is AvastUI.exe is detected as using the hardware acceleration…(the option to use graphical effects is turned off)
Is this inevitable ? Because if it is, i’ll have to switch to another antivirus…
What kind of “hardware acceleration” are you talking about? I use the EVGA Precision software to OC my videocard and I see no increase in the clock speed of the GPU if I open avast interface and start clicking around…
I do not mean it’s actually using the GPU or anything, i don’t get temperature augmentation.
What i mean is that the hardware acceleration is being used (and it might not be normal since it’s standard 2D stuff).
Here’s a screenshot:

As you can see hardware acceleration is at 1 while it should be at 0.
Might be a rivatuner problem but i didn’t have that problem with older avast versions…
It may be a bug in riva tuner. Like I said I see nothing going on when using EVGA’s software and I also have no problem playing games.
AvastUI doesn’t have to use “visible” 3D to use hardware acceleration ;D >>> i.e. it does use flash player, and as the latest version of flash player use hardware acceleration, so does AvastUI 
And no you can’t avoid it, because you can’t turn off the statistic panels. Animation settings concern only transparency for the pop ups and the spinning of the avast tray icon.
And on a side note, Windows aero (and not just flip3D) uses hardware acceleration >>> transparencies, taskbar thumbnails etc…use 3D accelerated calculations through Direct3D & DX10, based on your graphics card abilities.
So it only remains to unnistall avast, switch to another OS(DOS 
) ,and never use flash 10.xx and you’ll have your videocard free from any usage , lol, you must be kidding, that’s nonsense, you’ll switching from a good soft just because of that ??
@ Sparxx: you’re talking to the OP right?
Flash uses GPU acceleration for H.264 decoding, for the rest, it relies on CPU, and I really do not get the point of “hardware acceleration” graph. According to this post http://techreport.com/discussions.x/15710 for things other than the aforementioned decoding scenario, the acceleration has to be enabled by devs, i.e. content must be “optimized” in order to benefit from GPU accel - this means that watching those 1080p videos on youtube will see little to no benefit.
Ontopic:
I would get the point of a graph showing the actual core frequency of the GPU and percentage of GPU usage (i.e how busy your GPU is). I think the OP should try other "more"modern software for his tuning needs as Riva Tuner seems a bit old.

GPU-Z also shows many interesting stats, so if you can use riva tuner to do the OC, you can monitor the rest of the stats with GPU-Z while running stability tests and games.
Anyway, like I said, Avast will not hamper your system’s performance while gaming.
@ Logos, yep
okay 
Such ignorance… why are you even replying ?
I don’t want to monitor anything; i’m switching frequency profiles depending on the situation. A normal idle desktop should not be using hardware acceleration and that’s basically how you determine if you’re running a 3D application or not. If i cannont determine this, i cannot have profiles that auto-switch the frequency settings and setting them “on the fly” is quite annoying.
This is certainly a bug due to the new version of avast since as i said already i didn’t have that problem with older versions.
I might try uninstalling flash player though, maybe that’ll solve the problem. I don’t really care about the stats screen and as Logos said Avast does use that.
Windows Aero might use hardware acceleration to, but i never used it. I usually disable useless ressource consuming options on my systems.
Too bad i’m not having serious answers from the avast staff though =/ that’s what i wanted when i posted this.
Still, thanks for the answers…
What you’re calling ignorance i call well thought step.
By the way did you ever heard about sarcasm ?? You shouldn’t take it all personally, it was just a good slightly sarcastic advice.
Hope you understand what i mean, because i didn’t want to upset you somehow.
yeah, I can’t see any good reason why the desktop shouldn’t use hardware acceleration. Even the lowest end systems can handle that today. So, unless you’re stuck with a very old setup, you got no reason to reject current software behavior.
ps: tu te fais du soucis pour pas grand chose
Ici, je pense que nous sommes tous un peu comme ça!
@Faenrir First I’m not Avast staff, and as far as i know nor are the others that replied to your question. Second, in my last reply I already suggested that you should use other software to accomplish what riva tuner does and I also gave you a link where basically, they said that atm riva tuner is not being developed anymore and it’s old.
If you’re trading system security for what an old app says then fine, go, use whatever product you like and does not use “hardware acceleration”.
Yep, that’s precisely what i didn’t want since i wanted AVAST STAFF (therefore not you) to answer.
Works fine after uninstalling flash player btw, i have no use for it since i still have the plugin installed in the navigator and i don’t use any flash apps.
Anyway, for Logos : I know my system can handle it, but i need to monitor hardware acceleration to auto-switch overclocking / downclocking profiles.
When it’s 2D i downclock the card so it uses less resources (fans being run at 50% and the card being much cooler).
When i launch a 3D app, it’s detected and it then uses the overclock profile which boosts the card power and the fans are back to normal (i also have fan profiles that auto-switch depending on the GPU temp).
It’s really useful and if i hadn’t found a solution with avast i would have switched to another antivirus like antivir or anything else.
