Hi, I have some troubles when speedrunning. Sometimes objectboost and scripts (TC and BP especially) don't work as intended. I just don't gain enought velocity at TC, and on BP - box just flies away.

And what, you are gonna ask me? This only happens when OBS is active, mostly at streaming. (R3-4100+GTX970. Streaming via Nvenc)

So what exactly can it be?

I'm pretty sure that the obs requires increased performance from your computer, and it starts to lower the fps in the game, which prevents you from performing tricks properly. (speed depends on fps)

@Inv1ve, so how to troubleshoot this? I tried increasing priority for HL1 via taskmgr, didn't work. I tried disabling any kind of overlays in OBS. Only thing it fixed - Test Chamber skip (and still sometimes I don't gain enought UPS)

You can post a run without a video, but if you want to speedrun on a stream, you will have to find a less demanding program (such as Mirillis Action, but keep in mind that it has fewer functionalities than OBS).

try disabling preview (its called performance mode in streamlabs if you use that) also make sure v sync is off in nvidia control panel and one last thing is that maybe you are using goldsrc package and i had worse performance on it than 2005 version of the game so try switching to 2005

@EXT9ND already tried all of these. And using 2005 package from the beginning.

Sometimes it just okay, but anything can just break everything.
