This is the best one I've found for Rune Gold... http://kentie.net/article/d3d10drv
Does a great job...;)
On ebig difference is that dx10 simply doesn't have the GPU driver versatility when it comes to IQ settings. With dx9 and opengl, you can force SGSSAA via nvidia inspector which will increase image quality to levels dx 10 just isn't capable reaching.
Not sure how recent AMD drivers handle AA support for dx9, but for nvidia at least, dx9 or openlGL is the superior choice.
Well, the AMD Adrenalins allow you to easily force SSAA right from the game's driver profile--and many other things too, if you want. The GPU requirements of the game are so light by today's standards (I run an RX-590/480 Crossfire, WIn10x64 AMD Ryzen system) that 8x SSAA hardly affects the framerate at all...;) These really old games look similar regardless of what type of FSAA you want to apply--but I agree with you that SSAA always seems to look better...!
