Try turning off ALL video enhancements.

One of the causes of this can be overheating of the GPU. Another of the causes is too high clock rates in the GPU or the GPU memory.

1. If you have changed the clock rates of your discreet graphics card, set them back to default


2. If your running the OEM clock rates, make sure you have enough ventilation. You should be able to run stress tests like furmark or msi kombustor to stress it out and scan for artifacts. Dont just assume your OK, run the stress tests and scan for artifacts, and do it for a good amount of time under stress.

3. While testing 3, watch your voltages in the stress test. It might be your PSU cant deliver the power needed. Make sure you meet the power needs.

Yoiu could try moving your drivers to build 358.57

Thanks stewar_py and nullak for your answers.
I dont have any video enhancements enabled.
My video card is not overclocked and the case is open so it have enough ventilation. I also changed the power supply and the same problem occurs.
What's going on?
Today I will try another versión of drivers...

Which PSU make and model did you change too?

You cant just assume your setup is OK, you need to stress test the GPU for power and thermals, and then run artifact scanning on it. Those two pieces of software I mentioned are free tools. Its the only way to know your GPU / heat / power is OK for sure. It should both pass the gpu stress test for a long period of time, and be artifact free when scanning for artifacts.

I run with hardware acceleration turned off with a 3 year old I3 3220 processor from 2012 and it plays smoothly with no stutter. I think it's a little faster than your CPU. Perhaps a computer upgrade of some sort is in order.

Stewart his 750Ti is fully capable of accelerating all of the possible 3d bluray disc codecs, as the purevideo hardware in his GPU is generations ahead of what is required for that. He has no reason to ever touch the CPU, let it idle and get the GPU which is far more powerful for these purposes to do it.

While your CPU is faster than his, with hardware acceleration turned on the decoding wont ever need to touch his CPU at all.

It sounds like good advice, but you're saying that his issues may be caused by stress to the video card but accelerating 3D shouldn't be stressing it anyway

Youve misintepreted what I said. He should be stressing the GPU using stress tests to confirm the artifacting isnt a hardware / heat / power problem. Most of the time these artifacts are caused by improper installation, improper power. Sometimes the GPU chip itself has been cooked and is now defective. He needs to stress it to prove it can operate under stress and only those stress tests I nominated will do it properly if it can survive for some hours on it. If it fails the stress test, he needs to rectify the cause of it.

Fair enough, but the cost of a modern PC system is very cheap and might be worth saving many of hours of tinkering that may lead to nowhere.

Stewart the cost all depends on the hardware. The GTX 960 in my HTPC cost me $AUS330. The GTX Titan X in my main machine cost me $AUS1550. Beyond the GPU, if he wants a new CPU he'll also need for say skylake a new chipset motherboard that supports it, with the right CPU socket, he'll need new RAM etcetc.

Installation problems like a lack of cooling are pretty common and will still exist if he sticks with the same case and so on if thats what is at fault here. Stres testing is easy to do and establishes a known baseline thats vital for resolving these sorts of problems. Without test results users would be just guessing as to whats happening and whats wrong.

Well I play 3D bluray with a second hand silent HTPC that cost me $600 AUS and an ATI 6450 video card that cost me $50 AUS. You don't need to spend what you have to get his thing to work.

Mate it depends what you want to do with it. For example if someone wants to play high frame rate 4K content (like me) than its a GTX 950 at minimum and a GTX 960 at most. Theyre the GPUs that have the right version of nvidia pure video in their graphics video engine hardware to do full hardware decoding.

Sure, but I don't think the OP has the same requirements as you (a non typical power user of PDVD)
