ORBX or GEX without autogen

Hi

I purchased FSX-SE on steam when it was £5 and have recently installed it. For now, my hardware is not able to run it properly and until I get a new PC later in the year, I need to run it with autogen switched off in order to get a contant usable 30fps out of it (oi, stop laughing at the back!).

Until now I've been using XP9 with IVAO for all my flight simming which is great but it is nice to have everything, planning, ATC, AI aircraft all under one program with FSX.

However, graphically it looks very poor minus autogen compared to XP9, the tiling is repetitive, bland and kind of "bleached out" looking so I've been considering buying a replacement texture program to improve it, maybe ORBX or more likely GEX.

Does anyone have any experience of using these without, or with minimal autogen? Do they make a significant improvement in the way that FSX looks? All the screenshots I've seen to demonstrate both of these have dense autogen set which isn't an option for me. Can anyone post a screen shot of GEX or ORBX without autogen so I can have a quick look.

Also, apart from these two, what are the other alternatives?

Thanks,

Paul
