Ah right, you mentioned that before.
Can actually try it myself, i got 100mbps up/down so should be easy to identify if i have upload issues.

Watched it, and it looks goods as far as i can tell.
Artifacts sure, but can't really be seen during playback, and i am uncertain were tehy are as i can't compare it to the original.
And in that case, it's pretty much transparent:)

What's the CPU load at that settings?
What's the x264 load at similar settings?

Update:

Did this while writing, i uploaded your video to my own google drive, or well i started it.
And looking at Task Manager i get about 80-100mbps on Send, which means it's working as expected.

So the problem is probably not at Google Drive.

Though, i actually have had similar problems, the solution may be to change a setting in Windows, may be worth trying.

in cmd write:

Netsh int tcp show global

This will show the settings you have, you can copy them if you want, but probably it's all default anyway.

Try change the Auto setting to something.

Netsh int tcp set globla auto = high
(you can try, high,disable,experimental,restricted) think that's the names.

Normally you want, Disable, normal or highlyrestricted (you can write high for short, it works).

try change, and try upload, no need to restart your PC, if it doesn't change anything, just go back to the default which should be Normal.

Now, if you enable CBR and write max bitrate it won't vary so much, it will be about 3000-4500 if you set 3000 Kb/s,I mean in this way. But it only works for 30 and 60 FPS, when 45 it sometimes encodes with 10000 or even 20000 Kb/s.

Ok, looks like VCE actually uses fps for something then :P

E: Doesn't like 22 fps, but 23 and 29 is fine...

I think i have to add something like this to make 64bit work. I don't know why OpenVideo64.dll returns device id as 32bit. And with large app like OBS, shit hits the fan. Any C/C++ pros know how to manage this kind of mess? :D
struct some_struct_from_openvideo
{
unsigned int deviceId;
}

cl_device_id clDeviceID = reinterpret_cast<cl_device_id>(deviceId);
#ifdef _WIN64
// May ${DEITY} have mercy on us all.
uint64_t * ptr = (uint64_t*)&clDeviceID;
clDeviceID = (cl_device_id)((uint64_t)clDeviceID | ((uint64_t)ptr & 0xFFFFFFFF00000000));
#endif

I tried this thing with CMD, but it didn't help. However - I tried to stream in bitrate higher than 15k. Today I've got lower speed than yesterday, it's from local provider and it has better and worse days, and today on speed test I've got ~14 Mbps upload (yesterday was ~25 Mbps). OBS dropped a lot of frames, square was all red, but I opened NetLimiter to check speed (I don't have any limits set because it's trial that ended and limits doesn't work) to see the speed... For a while it was over 2 MBps, for the most of time it was 1-1,5 MBps... I don't know why uploading to YT is limited to 500 KB/s... maybe I have to call to my provider, maybe he set some limits for popular uploading services, I don't know :/

P.S
What's the difference between enabled and disabled CBR Padding?

I think if it is enabled, with x264 it keeps bitrate from falling too low and it keeps it around entered bitrate.
With VCE, i set a setting that header comment says it generates skipped frames to meet GOP (group of pictures) target, so maybe kinda the same like x264.

I've committed a fix for the sync issue when using hardware encoders, I'll try to make a release for it soon.

What's better in 64-bit version? I don't really understand what's better with 64-bit versions of anything... It can use more RAM to run smoothly?

EDIT:
I tested new 32bit build and I think it's worse :/
I only tested with Desktop on fullscreen and it sometimes dropped frames while encoding (I was only recording, not streaming) and the bitrate started to vary again. Previous version was better so I'm gonna use it for now, but I can make a few recordings with new 64bit if you want me to :)

Holy noob error. Ok, download again. But you should be able to use older ObsVCE.dll with new OBS build.

E: Hm, VCE generates IDR every 30 frames no matter what keyframe interval is set.

First of all, I know nothing about all the technicalities related to this. However, I will say that I think that this is an absolutely awesome initiative. Definitely something I was hoping for, but never expected to actually become a thing. I'll definitely be keeping an eye on this thread :)

What's ironic about this is that just a day or two before this really got working well for me I purchased Mirillis Action! cuz I had a few bucks in my Paypal account from some hardware I sold and got it for $5 off the home/personal version. Now I'm just using OBS heh. Action! is good, don't get me wrong but OBS has more features BY FAR!!!! I'll have to donate some money to the cause ;)

i might just be a complete novice but how do i change the quality of VCE besides just changing the bitrate?

There isn't much UI yet for that. Latest build automatically selects better quality settings if VCE should be able to encode fast enough at given fps/resolution.

Wow latest build is pretty amazing. Butter smooth with 60fps, no stuttering, cpu stays nice and cool and no more green line at the bottom :)
Datarate however, even when I set it to 3400, is still 6000+ so watch out when streaming to twitch.

Is it possible for you to make a UI for that later on? It'd be nice to further tweak the VCE settings. While the performance is absolutely phenomenal, it'd be pretty nice if I could get a little more quality out of my recordings.

Aye, I noticed the same thing. I won't be streaming with VCE just yet until the implementation's a bit more solid for streaming. It's awesome for recording, though :)

Since I'm sure some people will want to know: Which AMD video cards are required for this to work, or if its easier, which generations are too old / don't have the required logic?

It's stated in a link i provided earlier.

Pretty much, 7xxx is needed at leas, anything below that generation won't work (I got 6970:()
