Question / Help FPS lagging

[JIMGREEK]

Hello everyone,

I recently downloaded OBS to record a game (Euro Truck Simulator 2) but I have some problems. I tried both 'game capture' and 'window capture' but it says 'High encoding'. Do I have to lower the settings?

My laptop has:
-CPU: Intel i7-4500U 1,8 GHz
-GPU: AMD Radeon HD 8870M 2048 MB
-Ram: 16GB
-Resolution: 1920x1080

Also, in OBS settings, in 'video adapter' I can only find my second GPU which is: 'Intel(R) HD Graphics Family' which is not as good as my AMD GPU. Can my AMD be the video adapter (and how?) and is that going to make the videos better?

Thanks!

AMD unfortunately gives us no option to use it as the video adapter (Nvidia has such an option in its control panel) so we are often a bit screwed on devices with intel+amd graphics chips. BUT there are of course ways to get it working, could you first of all show us a log file:
Problem? Make sure to post a log and/or crash dump -- HOWTO
That will give us some more info about your setup to work with.

Here is my last log file attached:

You can't stream at 1080p with that CPU, it only has two physical cores. I would recommend using downscale to reduce CPU usage. (probably 1.75 downscale or more)

I don't realy want to stream, just record. So, your suggestion is to use downscale, but the video quality is not very good. Is there any other way to reduce CPU usage (reduce FPS or change the video format or lower the game settings for example)?

For recording you can also lower the encoding preset from veryfast to superfast or ultrafast.
To get a good quality follow this guide:
How to make high quality local recordings

In short, Bitrate 1000, Buffer 0, CBR off, and in the advanced settings activate custom encoder settings and add "crf=15" into the field, without the "". There you can also changed the preset.

if you want 1080p recording on that cpu and you dont play to record 1080p60 but 1080p30 instead then go ahead with settings like

1920x1080 resolution
30 fps
ultrafast preset
30000 bitrate
30000 buffer

or use a buffer of 0 and a bitrate of 1000 or whatever and the encoder decides how much bitrate is needed

Thank you all very much, I 'll try your suggestions and I'll inform you.
