VSync performs the exact same effect of capping rendering at 60FPS.
Also, the guy who said that monitors don't go over 60 is on the right track. The only reason to uncap your FPS is to check benchmark scores. It's rare that turning off VSync will actually fix any rendering issues.
There is one problem that VSync does create, though. That's a response time issue. Due to the VSync waiting for the right time to render a frame, so there's no image tearing, you'll suffer minor lag from input devices like your mouse. It's not huge, but it's there. You need to enable Triple Buffering to fix it. I can't remember if the SC2 options had VSync and Triple Buffering in them, though. I'll have to check that out when I get home.
Also, the human eye can typically notice changes up to 100FPS or so, btw. Though, you very much do have to focus. Anything above 50FPS tends to result in minimal changes as far as people are concerned. Anything above 85FPS tends to be problematic due to monitor restrictions.
There really is no reason to go over 85FPS at all unless you're benchmarking hardware performance. Pushing your hardware will only decrease its lifespan and decrease it's power gradually. Definitely less than ideal for anyone who is concerned with money.
Anyone who is concerned with keeping their card under 60°C is just being efficient.

This is a very very good thread to put into consideration, and especially since it is Summer temps will be reaching rediculous highs in your computer, so best be safe before frying hardware.
|
if only my sc2 can run over 10 fps at the lowest lwoest setting this would be very helpful
|
My laptop graphic cards can go up to 105 celsius :O It's qwazy!
|
I was looking into this issue before i found this thread..
my 8800gt went up to 99 degrees.. and probably more when i wasn't watching
i had to manually double the fan speed
so i've turned everything to low, except the CPU settings..i put those on ultra like effects, physics and cinematic quality, cuz they use cpu not gpu
frame also maxed at 60/30 now, thx
|
only blind people cant notice the difference between 60 and 150++ fps, the mouse precision, the response of the cursor moviments and other things are very noticeable, i would put a limit of 100fps, 100fps is fine, much better than 60.
Did someone ve ever played Counter Strike 1.6? THERE IS A HUGE, A VERY HUGE difference between 60fps and 100fps, thats why everyone uses the command fps_max 100 there.

Many GPUs can undervolt pretty well. I.e. GTX260's - mine came stock at 1.125v, but I can drop it to 1.088 or lower and it drops the load temps a full 10-15C's.

That's what I like to see. Going for taking care of the card, trying to keep your system in good shape... because it performs 90% and really good anyways.
It's obvious I'm concerned about keeping peoples gear in good shape and not trying to have some internet pissing-contest about who has more FPS on Ultra on a 30 inch monitor.
Overclocking to up your numbers to swell your e-peen is just- not me.
I like how my card can chew this game up and I can play comfortably for hours with no worries and no hours of babysitting my system. That's whats nice!

Question!
So if VSync causes a bit of mouse lag, if i set frameratecap=90 will that mouse lag only occur when my computer is restraining its FPS?
The reason i ask this is because normally my computer runs around 70-80 FPS which is perfect! But when little cut scenes occur it spikes to anywhere from 150-250+ depending. In those situations i wouldn't mind the extra response lag, but if my computer is constantly causing tiny bits of mouse lag i rather just risk it :O
|
Personaly, I always notice some screen-tearing if I don't have Vsync on.
Especially when I mouse scroll my screen. It's pretty slight, but bothers me to no end.
On the other hand, I don't notice or get bothered by any sort of lag. I'm not all that precise anyways.

hummm whats a good safe GPU temperature? 60C?
I use an ATI 5770 and run everything on ultra, the temperatures look like this
VSync ON:
Normal 61-63C FPS 60 - 50
High 65-68C FPS 50 - 15 (Campaign mission with 300+PSI and mothership, destroyed my FPS)
VSync OFF:
Normal 64- 65C FPS 100 - 65
High 68-70C FPS 50 - Untested
All test results are from the campaign, which seems to be more stressful on my computer, im not knowledgeable enough to know if 70C is dangerous for my computer or not :O

Afraid of 60C? My Crossfired HD4870's run at about 63C right now idle at 38% fan speed and I don't care. If I hit 100C the fan would automatically spins up to 100% to cool off the system. To date I've never found a game demanding enough to raise my temps by 40C. Keep in mind that 100C is still lower then the highest temperature the GPU can technically run at (something like 115C).
I'm also idling a little higher then normal because I need to blow out the dust in my 4870's fans. That will give me 10-15C lower idle temps.

I cannot begin to tell you the number of problems that result from auto fan speeds. You shouldn't need to hobble you GPU at all. Hell you have a faster card than I do, you should be running ultra HD like I do, no some pussy 60 fps, no offense. pussy 60 fps? You do realize that is quite a bit more than humans eye can register. In other words there is no need to play the game on 120 fps if you can play it on 60.
That's nowhere NEAR true.

It can't see color but it can distinguish change/movement it's not really important though because it's barely noticeable at those speeds esp for an rts it's not a twitch shooter.
You should use V-Sync for one reason. It removes screen tearing.

No, wrong again. The human eye registers different colors differently, and viewing angle also affects "fps" of the eye. This is a good article about how the human eye sees in terms of FPS.

Vysnc is great if you consistently get over 60FPS, but it really is unnecessary. A GPU running at 60C load is perfectly fine. The GT200 core that the GTX 260 is built around can take 80C without breaking a sweat.
Just about any GPU can take 80C-90C without a problem really.
|
My GPU (laptop) was running at 78ºC... so i decided to stop playing. Then i put forced vsync ON through the Nvidia control panel, and put some options to favor performance instead of quality now it hasn't gone over 65 so far. 
Remember everytime your PC CPU/GPU is operating above its ideal operating temperature it is ageing much faster.

Are high 70's and low 80's bad for my nvidia 320M? I'm on a laptop too :/ i hope playing sc2 doesnt fry my laptop
|
my card was running at 100 degrees C last night. I couldnt believe it when i looked. It never did that in the beta.

Niji, your long post is entirely 100% correct, until you get to the part I bolded; When you say "Decrease its power" do you mean the rendering power of the GPU, or do you mean it decreases the power usage? Either way that part is incorrect. The rest of your post however is great!

You should turn the settings up to as high as they will go while still being able to provide the framerate you require, then you should adjust the fan speed to provide a temperature you require. You should not think you have to sacrifice visuals or performance just to lower the temperature (unless you have the fan maxed and it's still a ridiculous temperature - in which case you may have either a defective card or defective thermal paste/interface material)
--------------------------------
For everyone wondering about safe GPU temperatures, EACH CHIPSET IS DIFFERENT (different die size, different process size, different transistor count/density) - therefor "Safe" temperatures vary wildly. YOU SHOULD MOST CERTAINLY LOOK UP THE SAFE OPERATING RANGE FOR YOUR SPECIFIC GPU (or gpu family)
