I assume you've tried d3d renderers? (directq, fte, dp all have d3d rendering available in some form).
Vanillaey gl engines are likely to benefit from gl_ztrick 0 (the better maintained engines will likely have this cvar defaulting to 0 because its actually faster on modern hardware, but you may have an old config).
For fun, you could try fte's gl renderer with "r_stereo_method 1;vid_restart" for stereoscopic rendering. DP can also do the same thing, but I'm too lazy to check what cvar you need for that.
These are not supported in d3d9 because d3d9 does not support stereoscopic rendering contexts (d3d11.1 does, but that requires win8).
