Re: Emulating GSync at fixed refresh rate? [triple buffer]

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

I really don't see how triple buffering could damage the graphics card.

This is false information.

I can confirm that the graphics card damage did not come from triple buffering.

Is OFFICIAL it that TB may not damage VRAM? Who did you say? NVIDIA? But...

I tested:
I quit OpenGL game/program without the wait while TB is disabled - GODD but I quit with ~2 sec wait while TB is enabled - BAD.

Software bugs can cause certain modes to crash (e.g. triple buffering) -- that's valid information.
But it does not damage the hardware -- that's misinformation. AnandTech, TomsHardware, TFTCentral, pcmonitors, BlurBusters, all agree that triple buffering does not damage hardware.

Damage can be caused by other factors such as running the GPU at higher workload (e.g. higher frame rates) with insufficient cooling. Triple buffering can increase frame rates, but so does VSYNC OFF. If this is the case, your cooling is defective -- fix that first. It's not the triple buffering's fault that your GPU overheats at higher frame rates. A GPU is always designed to never overheat/crashes at maximum frame rate, so if it gets damaged at maximum frame rate, it is either a cooling problem (nonworking fans, blocked vents) or a warranty claim. Sometimes, in the past, some GPUs didn't have proper cooling for their maximum workload in an average computer during a midsummer day. Newer GPUs are now better designed to prevent this from happening.

Also, the long chinese whisper (clicky!) chain probably distorted your information from "'higher framerates can overheat GPUs that don't have good enough cooling, and damage them", and turned that whisper into incorrect information such as "triple buffering damages VRAM".) Give your original source a big nudge, and correct them on their mistake. ;)

@admin: Thank you for your information! :)

I have bought new EVGA GeForce GTX 480 by 410€ on november 09th, 2010. :D I do clean dust in PC tower monthly to avoid videocard damaged since december, 2010 after read importants of EVGA. :)

It is possible EVGA suggested turning VSYNC ON instead of using VSYNC OFF or using triple buffering, as a "band-aid" to prevent an overheating graphics card / graphics VRAM. It's not 'underclocking', but it's a way of throttling & slowing down your graphics card to make it generate less heat.

Adding better cooling (e.g. more airflow, replacing fan with better aftermarket fans, etc) would nullify the problem too as well.
Also, the GeForce GTX 480 was also a power hog, and ran VERY hot:

If you pay for your own electricity, you may even save a few dollars a month in electricity costs by buying a GTX 760 since it has a lower idle power consumption if you run your computer 24/7 (new cards have better power management to let them idle at lower wattage.)

I always use v-sync without TB for play/interactive games, interactive demos/samples and watch multimedia. :)

I don't need new cooler because I'm satisfied stock cooler -- no BSoD/freeze but I use custom auto-fan and don't OC (but especially OC sometimes ;)). :D While I disabled vsync for benchmark (programs/games).

I'm not worried despite high power and hot but I tested and got 91 ºC@100% fan (summer - 30 ºC in my room lol) in Furmark running GTX 480@stock. ;)

I deserve only top-end single-GPU videocard (eg: GTX 28x, 480, 580, GTX Titan... except 680 due to the crap die). I want GTX Titan (in case of GTX 480 died) for "fast" double precision but I will buy NV Maxwell or Volta. ;)

EDIT: look my signature. ;)
EDIT2: ooh! Voila - bad but yes Volta. ;)
