I run Simrail on a 1080-1920 tv screen. Do I need to upscale or do I just use the anti-aliasing options ? I have Nvidea RTX 2070 which I believe supports DLSS. I do not notice any difference either way. Possibly the DLSS setting is a little better but it is hard to tell. I thought upscaling meant improving the display on higher res. monitors than my TV.
