Slow Decoding

[Acid Caribou]

I tried home streaming tonight with Bioshock Infinite, and the performance was pretty poor over a wired gigabit connection on both ends. I kept running into "slow decoding" or sub 60FPS frame rates during my session, and I don't think hardware is an issue.

My streaming desktop is an i7-4770k with 2x 7970 GHz Editions + 16GB Ram
The receiving laptop connected to HDTV over HDMI is an i5-3220M + 8GB Ram.
Both systems run Windows 8.

I also noted issues with sound "pops" coming in over the speakers.

Here are links to a few screenshots.

I tried turning hardware decoding on / off on the laptop, and off was worse. The laptop was also plugged into an outlet, and I made sure no throttling was taking place.

It looks like you've set your bandwidth to "Unlimited". This has huge impact on encode and decode performance.

Try setting the bandwidth back to "Automatic"

I'll try that tomorrow, appreciate the advice and keep up the good work, amazing progress for a beta!

Thanks! :)

This fixed the problem by the way, thanks.

Great! :)

I had the same problem, and made the same mistake. Now I can play Skyrim full modded right from my bed. :P

But do you know why setting on unlimited does this?

Hi,
I also experience slow decode, but my with default settings (automatic).
I played CS:GO and most of the time I had about 15 fps/s.

My host pc:
CPU: AMD Phenom II X4 965
GPU: AMD HD 5870 1GB
RAM: 12 GB DDR3 1333MHz
Network: Conntected via Powerline Adapter
OS: Win 8.1 Pro x64

My laptop to which I stream to:
CPU: Intel Core i7-4600U @ 2.1 GHz (Haswell Ultra Low Voltage)
GPU: Intel HD 4400
RAM: 12 GB DDR3L-1600Mhz
Network: WiFi
OS: Win 8.1 Pro x64

I had the taskmanager open during streaming.
Couldnt see much cpu load after I closed the game, dont know about GPU load.

Is my laptop just too slow to decode?

[Acid Caribou]

People stream to much lower end hardware, it's not the client. I remember latency on powerline adapters being really poor, you might be better trying Wi-Fi.

make sure that you have installed the dx9 redistributable. on a fresh installed win8 it doesnt come installed by default but it is required for the hardware decoder. without it you are stuck on software decoding which can be slow.
