Let me start by saying I have been streaming for over a year now and have read a great deal of the forums posted here. What I am trying to figure out is, why, even with a dedicated streaming pc, I get so much blur and artifacting on my twitch stream. My pc's are as follows

Gaming PC
i7 4770k
GTX 980
Asus Sabertooth z87 mobo
120gb SSD
16 GB Hyper X Beast Ram
750w PSU

Streaming PC
i74790k (overclocked to 4.8 Ghz)
MSI z87 Gaming Mobo
500 GB ssd
Avermedia Live Gamer HD
Microsoft life cam studio edition hd
8 GB G skill Sniper Ram
750w PSU

The issue is, no matter what settings I apply in obs, my stream is often blurry and lacks detail. Colors seem washed out and the stream just lacks hard edge quality of image. I do know that a 1:1 is impossible in stream, but this isn't even close and I would think that I should be able to get closer.

I should also say that when I am on my desktop, I can easily get perfect stream quality (like when I'm messing with my audio settings and streaming it for people who want to know how I set up my audio.) but as soon as I hop in a game and there is lots of movement the quality goes bad rapidly.

I am using an Avermedia Live Gamer HD. Are there some opitmization settings I should be applying to the Avermedia card. I just get the feeling that the Avermedia is acting as a bottle neck.

I would post images of my OBS settings, but believe me when I say I have tried EVERYTHING. 720p at 30 fps, 720 at 60 pfs, 1080 at 30 fps, every cpu presset, etc. I can put this comp on any setting you guys tell me to, and I will! Just help me get a little more clarity out of it.

60Mbs Down, 5Mbs Up Internet speed.

Tell me what you think in terms of settings and I will put them in and try it.

Fast forward this video to 20:00 minutes in. It will give you a good idea of what I talking about.

This video was taken at a 3000 bitrate, with a 720p downscale with a bicubic (I don't always use bicubic, but none of them appear to have an effect.) on the Fast Cpu preset.

Any Ideas?

Hi blah,

You are asking for the impossible really. Your stream looks as good as it should with that set up and that bitrate. By the very way in which encoding works fast moving scenes are going to look less detailed than static ones.

What you can try is looking over here: http://gamerzone.avermedia.com/game_capture/live_gamer_hd

See what happens if you use the latest AM-LGHD drivers (released this week). I've been having a ton of trouble with these recently as they seem to cap my framerate in OBS at 30fps, It would be interesting to see if you get a similar problem.

I've been noticing AM-LGHD and OBS are having some issues when used together in the past few weeks at high frame rates (60fps), I have no idea why and no-one seems to be able to shed any light on it.

Out of interest do you notice any stutter/judder for short periods in OBS preview window?

I don't really notice a lot of stuttering. I did yesterday turn the CPU preset all the way down to "slow". My cpu didn,t even mind, i think it only got up to like 75% usage. But when I did that there was a large amount of punctuation in my obs preview window like it was dropping frames, except it was not dropping frames. Then that stutter did show up on my stream as well. I don't know what the cause of that was.

I'm going to get on those drivers right now and see what effect they might have and I will report back here.

Would you happen to know what "deinterlacing" and "video standard" and such settings in the AV-LGHD configuration will do in obs? I have always had a feeling that if these where tweeked and set up properly I could milk some more quality out of it. I always feel like the card is a bottleneck.

Did you manage to test this?

There is something seriously broken with the OBS/AMLGHD combo right now and yet no-one seems to be talking about it.

Ya man i did try it... I am having no problems. I would try putting the card in another pci slot and/or getting a buddies capture card and trying it in your pc. You might have a busted card? Contact avermedia for a replacement perhaps?

Okay so you guys are using the new RECentral package from http://gamerzone.avermedia.com/products/live_gamer_series/live_gamer_hd/download/en and having this FPS issue correct? Does rolling back to the last driver package from http://www.avermedia-usa.com/avertv/product/ProductDetail.aspx?Id=513&tab=APDriver fix the issue? You don't even need to install RECentral, the driver-only package should be sufficient.

(Cross-posting to a few different threads about this issue instead of merging them all into one)

Sapiens: As per my suggestion of rolling back drivers in my own original thread it only seems to 'partially' solve the issue.

The latest drivers limit 720p capture at 30fps.

Rolling back to previous drivers 'appears' to fix the problem but if you preview a game for long enough you will see 'stutters' in OBS where the capture temporarily and periodically limits itself again.
