Intel HD 4000 issues

[Hadzi]

Hello fellow gamers, This question has been posted a few times but i have not yet found a working solution. My system specs are:

Processor: Intel i5-3320M 2.60 GHz
Ram: 8 GB
Graphics card: Intel Graphics HD 4000
OS: Windows 10, 64 Bit version

Game log at following pastebin:

I'm getting Invalid framebuffer operation (1286) on Intel HD 4000 on beta versions. Any solutions ?

For a little while now the game hasn't played nice with integrated graphics chips. I'm not really sure what if anything can be done about it.

I may have stumbled onto a solution, simply downgrade the settings down, eg: turn off double size textures, turn on simple textures for weapons, players and Zombies, Turn off Multi thread (multi core ?), reduce fog, water, puddle quality, turn off dynamic skybox. The game will not look pretty but for me gameplay is important. Basically reduce what you can.

Played 2 hours so far, log is clean no framebuffer operations (I restarted game twice and started a new game 3-4 times to test it). I played on Legacy_41.60 beta.

correct, turn down to minimum, light-update sources (something like that its called), turn it down to 5 or 10. Turn down fog to the classic legacy fog, turn down reflections, turn off all the water puddle and also turn down the water quality. Flora sprites affected by wind also affects performance, you can also disable weather animations when you're inside buildings.

you can also lower game resolution to something like 1280x720 or 1360x768

You can play with double textures no problem, just avoid to zoom out too far, you can disable zoom above 200% as well. you can also turn off simple textures for weapons, players and zombies.

Tested this on a IntelHD3000 and the game was around 30-50fps for the most part, very playable, if you use Rivatuner you can also lock framerate to 30-31 and the game feels more consistent that way.

Also, no matter what you do, places infested with 300 zombies are going to be laggy no matter what, even on high-end computers so keep that in mind if you're trying to create a custom world with increased zombie spawns

Also keep in mind that the first time you launch a brand new world, it takes a bit of load to generate around your character position, after that it should go smoother, you can also save-quit and then load the game again
