ATI Radeon HD 4000 Series discussion

micro-stuttering is the result of AFR solutions, and it happens due to each gpu frames synchronization.

Example:

GPU1-> frames 1,3,5,7,9,11,13 @ 0,01sec 0,05 0,09 0,13, 0,17 0,21 0,25

GPU2-> frames 2,4,6,8,10,12,14 @ 0,02sec, 0,06 ,010 0,14 0,18 0,22 0,26

If you come to notice, there is a 0,03sec gap between GPU1 and GPU2 frames, and that's the micro stuttering thing, while you have 2 frames displayed by each gpu one imediatly after another, but then you have a 0,03 gap.

This is just a quick example nothing really deep.

I hope we mean both the same thing.
I've made ton of graphs visualizing microstuttering, and it appears in cascades. For example the frametime-differences alternate beetween 10 and 60ms.

this stutters


this not

Read what I wrote again. How is "the CPU delivering the processing data too fast" different to "the frames are not distributed evenly in game time" ? Obviously game time is controlled by the CPU. Don't argue just for arguing sake...a little reading comprehension goes a long way.

Because the unevenly distributed frames are a result of the too fast cpu
cold is the result of viruses...i don't have a problem understanding this
but this is a way too ot for now

Man, I just made a quick example, nothing very deep, so yap, your example is perfect, I just made through a quick mind example nothing more.

Actually, micro-stuttering is a very easy deal to understand

maybe, but both ati and nvidia ignored it for several years now.

Doubt it, but if they did than this could imply that micro-stuttering is a rather easy thing to fix through drivers. If they already knew about it for a while, let's say at least a year, then the fix is probably not very easy.

I suspect vSync fixes it, i only noticed micro stuttering when I had 8800GT SLI, Crysis @ very high vista x64 40 fps seemed like 18fps, weird thing :s

I didn't try vSync though, although pasting 60fps, micro-stuttering isn't noticed because frames displayed are enough to keep fluency.

All this talk about dual GPU cards brings back memories of my old Rage Fury Maxx. I thought we were on to something then, putting two GPUs on a card. Guess it took a couple years longer till the idea came around
