Alright, so, this has been getting worse for a while and now I just can't live with this shit.

This stuttering is driving me fucking insane when using polymer.

I've tried all kinds of shit. Even weird stuff like setting the flip queue size (prerendered frames) to zero.

I have a Radeon 6970 and I'm running it at 1920x1080.

Any ideas? I recorded this with my phone, I wasn't sure if FRAPS would pick it up.

Sorry I just reflashed my phone. Lost my YouTube settings. Why the fuck is that the default?

Just fixed it.

Double post. Here's another one. I'm 90% sure this is lighting related.

yep. that's polymer lag. i used to get that with my old 9800 gtx+ in some bad spots.

my old card and new card use the exact same divers; maybe it has to do with DirectX/Shader Model Support

Well, have you tried disabling lights (r_pr_lighting)?

I can only speculate because I tried rotating in the way the video shows in this specific part on an AMD machine with HRP and didn't encounter the hitching. The two most probable candidates are loading highres textures and linking shader programs. But neither seem to apply here: first because you're using the low-res tiles, and also because both should happen only on the first texture loading / shader creation. Is it really hitching, i.e. the slowdown is transient at the midpoint of the player rotation, or can you find an angle midway where the FPS is (presumably, significantly) decreased?

Viper is the kind of guy that can detect the difference between 59fps and 60fps

Getting this same problem.

May I remind you two that I posted two sentences ending in an interrogation mark earlier, aka "questions"? Answering them may or may not shed light on the issue, but ignoring them is guaranteed to not move it by an inch, at least from my perspective.

iirc, my issue was angle
looking at the vids, it appears to be the same for V

[Helixhorned]

In other words, yes, you can find an angle with significantly lower FPS than the surrounding? The reason I asked is that you could try to profile EDuke32 at the two positions then and maybe see where the bottleneck lies. Under Linux, I'd use sysprof (super-easy), but for Windows, I don't know what people use for profiling tasks. There appear to be various vendor-specific developer tools like AMD CodeAnalyst.

By "transient" I meant that the hitiching occurs for a short amount of time without the possibility of finding a "bad" position. In that case, profiling likely wouldn't give much insight.
