[other] Problems with dropping frames with EVR (3 Viewers)

[tourettes]

Since the number of people using an ION board is increasing rapidly where in the range of low-end GPU -> high end GPU would you rate the ION?

no clue what it has inside

Mine is never using more than 64 % GPU even with HD so i would assume it's fast enough or can't the function the GPU offers just no be used for H 264/AVC-1 decoding and therefore it's still lagging for HD decoding?

when render target is 75% after v-sync, 64% sounds bit too much.

newer dll in new post

if (*pNextSampleTime > (m_rtTimePerFrame/2))

Please test following DLL. Should give more time for low end GPUs to render the fram (actaully 100% more time). Seems to work as well with the GT220 (with only quick testing...).

testedthis one. Unfortunately, it's not reducing anything... I reverted my changes and did the following:

if (*pNextSampleTime > (m_rtTimePerFrame/2))

and

if (*pNextSampleTime < -3500000 && m_bFrameSkipping && !m_bDVDMenu && !m_bScrubbing)

So your posted dll with the second change is working on my ION. I'll attach this one for others with ION...

This is also a more fine tuned version which adds a break when we are more than one frame too early

tested, terrible stutter still.

not as bad with cuda accel enabled, but still noticable.

disaster123:
I tested your patch. It works better if done like this (for me):

if (*pNextSampleTime > m_rtTimePerFrame/[B][COLOR="Red"]2[/COLOR][/B])
     {
     // Log("Sleeping: %.2f ms %.2f ms %.2f ms %.2f ms", (double)(*pNextSampleTime - (m_rtTimePerFrame/4))/10000, (double)*pNextSampleTime/10000, (double)hnsLastSleepTime/10000, (double)m_rtTimePerFrame/10000);
	  Sleep( (*pNextSampleTime - (m_rtTimePerFrame/[B][COLOR="Red"]2[/COLOR][/B]))/10000 );
     }

and this one? https://forum.team-mediaportal.com/575295-post223.html

This results in smooth playback on my ion.

woops, was just testing both with cuda accel disabled. retesting now.

I think you nailed this. I bet if you couple this with tourettes patch it should make just about everyone happy.

I hope tourettes can say something about my patch. It is running for SD and HD absolutely smooth for me.

One (maybe silly?) question: Do those changes also affect VMR9 playback or are those changes only relevant for EVR (and thus irrelevant for XP-users)?

to all ion users could you please try this one?
