Downsampling in TS2013 nvidia cards

[peterhayes]

Hi All
I've posted this on another forum but would welcome feedback from all RWA members that may not see that post
Has anyone tried the technique of downsampling to improve the visual appearance of TS 2013 with a minimal setting of ingame AA?
The technique looks interesting -but say I have a monitor with a native resolution of 1920 x 1080 and it supports a downsampling resolution of say 2560 x 1440 which resolution should be entered into TS 2013 the latter ie 2560 x 1440 or the former.
Has anyone who has used the technique seen any issues with TS2013 - I'm loathe to make changes until I see some more opinions or simmers with experience of the technique.
The technique is discussed here: http://www.neogaf.com/forum/showthread.php?t=509076 and here http://forums.guru3d.com/showthread.php?t=346325
If it works it could remove some of the shimmering effects seen on some routes in TS 2013 and give reasonable frame rates.

My buddy uses and swears by it. I haven't had the time to set things up here yet, but I've been thinking of giving it a whirl this or next weekend.

Had a quiet afternoon so gave this a tryout. On the two scenarios I use regularly for testing out possible improvements (on WCML-N and Settle to Carlisle) there seemed no doubt there was an enhancement in the graphics. Shimmering OHLE seemed to shimmer much further away in the distance, bare trees didn't look like a plague of locusts had descended upon them, and the graphics did seem sharper overall. However, as I increased from my native 1920-1080 the fps took a major performance hit. By the time I got up to 3200-1800 the sim was reduced to a crawl. There are warnings that you lose fps in proportion to the resolution increase, but given we don't seem to have much in the way of fps to play with in the first place, (if you're running on high settings already), then the payoff is more than cancelled out, at least for me, by the increase in stutter. Maybe it favours games where users are already running at fps far in excess of what TS2013 users can expect so there is scope to trade off fps in exchange for improved graphics. For information's sake my setup:

AMD FX-8150 stable @ 4.20 GHz
Gigabyte FXA-UD3 motherboard
16 Gb DD3 13300 hz memory
Windows 7 64 bit Home Premium installed on separate 256 Gb SSD
EVGA GTX 660 Ti GPU
Steam folder on separate 128 Gb SSD
Asus Xonar sound card
All in game settings at max except FXAA + FSAA 2X2.
Fps locked at 30.

Gone back to my native resolution for now, unless anyone can tweak this some more. My search for the Holy Grail of TS2013 performance continues.

Have you tried this? It made a big difference on my system. Did not check fps before and after, but the image quality was improved vastly !

Thanks for the reminder. Next thing to try. Cheers.
