I recently installed quake 2, but I cannot get it to run smoothly. In vanilla Quake 2 I get exactly 83 FPS. Changing the resolution does not change the FPS I get. In Quake 2 XP I get around 24. If I lower the resolution from 4K to 1080p I get around 40. Turning all the visual stuff off adds about 5-10 FPS to that.

And I don't understand why. I am running it on a laptop with a 7700HQ, a Radeon 560 4GB graphics card and 16GB of ram.

Things that I tried so far:

- Updating my graphics card drivers, no effect
- Reinstalling Quake 2. I briefly got 250 FPS when I turned 8 bit textures off, but then when I installed Q2XP again hoping the problem had solved itself, I got the same low framerates in both XP and vanilla.
- tinkering with the config file. I tried adding set r_primitives "2", no effect.
- the frame rate cap is 600fps
- limiting the game to one CPU core. no effect
- running clockblocker to prevent my GPU from idling. no effect

The weird thing is Quake 3 Arena runs like a dream, in 4K with 16x AF and 8x MSAA.

So why $#%@$@#$# can't I get Q2 to do the same?

Can you guys help me out?

Thanks for the tip. My FPS in Q2 vanilla is now 300, as it should be, but in Q2XP I'm still stuck at 24.

So you do not have troubles exactly with Quake 2?

I still have the same problem with Q2XP
