Topic: SVP Suddenly lags after switching to new monitor & display port

Hi.

I was running SVP recently on my 24' 1080p. Even on 4K videos, my GTX 970 + i7 4790k could handle it.

However now I switched to 27' 1440p and DisplayPort. No matter 1440p or 4K, says SVP performance too low and lags awful.

What do you think is the problem? The native desktop resolution rendering matters? Or is it the displayport cable?

Re: SVP Suddenly lags after switching to new monitor & display port

what card is rendering video? for example hd4600 may fail to render 1440p @60 fps (depending on renderer settings)

You can look to additional info (SVP tray menu - Information - Additional information). What resolution of video after all resizers?
I think it is profile setting Decrease frame size - To screen size. In your case with two monitors SVP handles 1080p and 1440p picture. The complexity differs in 2 times (2MP and 4MP). You need to add new profile for 1440p and for 4K and adjust profile settings.

Re: SVP Suddenly lags after switching to new monitor & display port

GTX 970 is my GPU. When I made 1080p my native desktop resolution, the problem is gone. So native 1440p resolution is buggy with svp. Any video lags with 1440p native desktop. Maybe SVP bug?
Edit: I have 1440p and 4K profiles. I changed frame size to disabled. Problem still here.

Good. Now you need to change another settings in profile window and save them to 1440p and 4K profiles to reduce CPU load.

Re: SVP Suddenly lags after switching to new monitor & display port

Hi, which settings exactly? I disabled frame size to both profiles.
I don't wanna touch "Frames interpolation mode & SVP Shader" as they make the smooth effect the most.

PS: I don't use two monitors, just one - the new 27 inch.
I was only explaining that everything worked perfect before, but turns out my native desktop resolution causes problems.

If I switch back the desktop resolution to 1080p - problem solved. But on 1440p native - nope.

I don't wanna run 1080p desktop on 27 inch only because of SVP.

With 1440p desktop resolution even some 1080p videos lag. I can't run any 1440p video on SVP if my desktop is 1440p too.
If I increase processing threads from auto to 8 - the cpu load drops by 20%, but it starts lagging even more.

Possible a bug you can look into? Or 1440p desktop resolution takes too much CPU resources? I feel like my hardware is already outdated... and I bought everything last month.

Re: SVP Suddenly lags after switching to new monitor & display port

The only thing I can think to try is to try enabling "D3D Fullscreen" in MPC-HC.

Other than that, you can try this cheaty work-around in MPC-HC:

1. Enable "Use autochange fullscreen monitor mode"
2. Uncheck all the resolution modes except for the top two - 'Default' and '01'
3. Set the "Display mode" for "Default" to your normal desktop resolution of 2560x1440
4. Set the "Display mode" for '01' to 1920x1080
5. Set the "From FPS" for '01' to "1.000"
6. Set to "To FPS" for '01' to "125.999"
7. Enable "Apply default monitor mode on fullscreen exit"
