Here a my settings in eng.cfg:
use_hmd = false,
stereo = (stereo_config) {
eye_separation = .1,
lens_separation = 0.0,
convergence = .065,
screen_size = (float2) {
x = 0.0,
y = 0.0
},
resolution = (float2) {
x = 0.0,
y = 0.0
},
eye_to_screen = 0.0,
scale = 1.2,
K = (float4) {
x = 0.0,
y = 0.0,
z = 0.0,
w = 0.0
},
aberration = (float4) {
x = 0.0,
y = 0.0,
z = 0.0,
w = 0.0
},
reduce_grass = false,
force_native = false,
stereo_type = 2,
swap_sides = false
}
System specs: gfx 560ti/314.07 win7-64 with Asus VG27H hdmi (3d top-bottom half).
Since I'm used to high separation settings maybe this is causing the artefacts.
