Hi,

I have been using OBS quite a lot, recently I had been forced to reboot my Windows to a fresh one instead, now, when I installed OBS I have encountered errors whilst trying to stream with Nvidia NVENC as encoder, since my CPU is quite bad and my GPU is better I have always used it to encode, another thing I've noticed is framerate drops in stream, my ingame fps is around 80-90 while stream fps drops to even 5 fps. Now all my drivers are up-to-date (checked it twice) and I'm using latest stable version of OBS, can't seem to remember if it was the same version I had before but I know for sure I didn't encounter "Encoder initialization failed!".

This is my log file from OBS:

How come? As I said, last time I used the OBS it was probably the previous version and it has been running on Nvidia NVENC just normally didn't have different GPU or anything but it worked fine

Actually it does support NVENC... contrary to what NVidia said day 1. (Don't know when they unlocked it).

The issue is that NVENC is broken in 0.658b. Seeing as that Classic is dead, you'll need to update to Studio 0.15.4.

Thank you very much c3r1c3 I had OBS Studio but I've lost myself into it couldn't make it setup properly, anyways thank you very much for your help, I'll look out for some guides for setting up, there's another thing I wanted to ask, I'm planning to upgrade my PC, now, since recent upgrade (GT 740 and additional 4GB of RAM) I was thinking of upgrading my CPU. But the problem now is, I'm clueless as what to do next.

My setup is:
CPU: AMD A6-6400k 3.9GHz with Radeon
GPU: Nvidia GeForce 740 2GB DDR5
MB: Asus F2A85-M
RAM: 1 Kingston 4GB (833MHz) + 1 Kingston 4GB (1600MHz) [Yea i know both are now 833]
PSU: No-name PSU with 450W Power

Now, I'll probably have to get PSU aswell since it is low if I am correct, but apart from that, what would be the best thing to do first?
Again can't thank you guys enough for the help you provided in such short notice. :)

The Power Supply should be good for what you have. All AMD APUs are weak, so even if you upgrade the CPU to the most powerful available ( AMD A10-6700 Richland Quad-Core 3.7 GHz - if you're limited to a FM2 CPU, and an AMD A10-7890K with Quad-Core - if your MB supports a FM2+ CPU) is still fairly weak.

That said those CPU upgrades would basically double your CPU power.

Moving to Intel would require a new Motherboard, and possibly ram.

http://www.anandtech.com/bench/CPU/53 Gives you some idea of what CPUs would be more powerful for encoding x264, so take a look at that and see if there's something in your price range that you can afford.

Thank you again for you answer, I am aware that APU's don't give out that much of CPU power as regular CPU's that is why I intend to remove completely A6 APU with a brand new CPU. Was considering AMD FX 8350 since in my country it's currently on discount and it is veeeeery cheap, gonna look do research about that topic a bit more before making a purchase, but thank you for everything :) you really helped me today :D

The only AMD FX-chip worth upgrading to is the 8xxx or 9xxx series.

Even then they are still weak, but at least they'll double+ your current CPU power.
