As the title says. I'm having near 60 FPS unzoomed, but as soon as I start zooming in, the FPS drops. The more I zoom, the more it drops. Max zoom of the M24 for example I'm left with +/- 15 FPS.
Using 1280x800x16, 16bit z-buffer.
Any clues?
When tested I did not change aiming position ofcourse.
The overall FPS increases when I lower the resolution, however, the ratio at which zoomed FPS is reduced compared to unzoomed FPS, is roulghly the same: 4.
i think it has something to do with the way the engine controls the texture LODs, such a quick demand for the textures to gain LOD might cause the Engine to lag a tad.
