On one of my workstations has Intel G41 chipset with built-in X4500 videochip. My Spring graphical setting are as low as possible. Most of maps are nicely playable (60-90 FPS), but on some maps in some areas FPS drops to 1. Here is an example (map is FolsomDamDeluxeV2, with water). On the first screenshot FPS is ok, but when i move camera slightly to the right it drops to 1. Draw world consumes 98%. CPU is loaded too. What's the nature of this drop? Some graphics computations are redirected to CPU? What does exactly cause this (because as i told above this happens on some maps, not every map)? Why second core is not used for graphics computation?
Are _all_ the settings at absolute minimum? It took me some tinkering to get my onboard playing nice when I still was using it. I found that even minimal decal settings caused catastrophic performance problems... and turning on shadows, even when they weren't being used, did similar problems. Also, try the ATI fixes and texture compression options.
Thanx for trying to help. But your answer is kind of a boring bot answer triggered by tags "intel" & "graphics". I do have another desktops. I'm just interested why this problem occurs (cause it is not usual FSP drop) and what's the original source of this problem.
Video mode set to 800 x 600 / 32 bit [ 0] SDL: 1.2.10 [ 0] GL: 2.0.0 - Build 126.96.36.19982 [ 0] GL: Intel [ 0] GL: Intel Eaglelake [ 0] GLEW: 1.4.0
I'll try to update drivers soon but last time i did it my DVI out died. Had to rollback.
