zDoom32 Sometimes Runs Extremely Slowly

[yuljk]

Hi - I'm running the latest release of ZDoom32 ona laptop with an Intel HD 3000. I find that sometimes when I launch the game the menu runs at a crawling pace as well as the game. If I close and re-open a few times it will run perfectly again.

I'm running with the OpenGL render and latest Intel HD 3000 drivers. This issue has plagued me with other variations of gzdoom. I suspect it is related to the OpenGL renderer.

This happens with just vanilla Doom or Doom2 iwads and any mods.

Here's a log:

]quit ` Any ideas how I can fix this? - It seems to be pretty random.

I should also note I'm using wtfi.exe in order to get around the 'OpenGL not accelerated problem' on Intel graphics.

Sorry this is a technical issue, probably a driver problem. If it happens also with D3D then something is running in the background eating cpu cycles. Have you tried switching fullscreen off and on? Or try borderless windowed mode (win_borderless), it's supported but not in the menu (there were a few minor problems).
