Laggy playback

Hi,

I've been trying to set up a projection and blend it with 4 projectors. The playback is laggy. What can be the problem? I'm using computer with spec:

i7 3770K

8 GB RAM

Radeom R9 290

SSD hard drive 32 Gb

I'm using windows 8 (due to other on-site requirements).

 

I think that this setup is strong enough to cope with four projectors, but lag is big, wideo can stop for a second. What can be wrong with it?

I would disagree.

Of course, encoding is the big variable, both codec, and codec settings can have a big impact on this.

but for encoding to best quality using Dataton's recommendations,

I would not expect four simultaneous 1080p30 decodes on that platform.

When selling hardware for a project with that spec,

we would not recommend a mid-range performer like your spec.

Three is more realistic for that spec.

Hi,

So what would you recommend to change in this setup?

 

Motherboard, processor, and four channel memory (4 ch memory must be supported by the motherboard / cpu).

A bit of overkill,

but an x79 based motherboard with an i7 Extreme Edition cpu and appropriate memory should do the trick.

Also, SSD speed / throughput is important, capacity is irrelevant to performance -

sustained throughput is what matters,

evaluate your current SSD choice from that perspective.

The gpu is not much of a factor as it relates to movie decoding, so it should be fine.
