Thanks for the input Tonto.
Checked and added the semi colon, also tried no SLI. Alas I'm still stuck at low res. Screenshots all show as 1024x768. Wierd thing is in both d3d9.cfg and main.cfg no such res exists even when at default

I've also tried synchronizing display in options. Still no difference. I'm totally stumped. FWIW I've tried the res fix at each different patch stage, then uninstalled and started afresh each stage with a new/fresh ACT fix.
I am now almost resigned to never getting back the glory I once had

Seems I am now in your hands shipmates, more than ever.
Best regards.
