- ENBSeries 0.075 Deus Ex version + ENBSeries d3d8-to-d3d9 converter
(original config sucks very much, so I've spent several hours making a new one to create one with a good post-processing effects - I can upload it)
- UWar Grass 1.23b
- AEC Islands Pack (basically WGL Texture Replacement Pack + Berghoff's trees)
- NIM Dynamic Weather
(for 3D Crysis-styled clouds, falling leaves, snow blizzards etc)
- GRAA3 infantry modpack
- SJB Weapons pack 1.1 + self-made patch out of a few never-released SJB Weapons pack 2.0 details (like better looking
AN/PEQ-2 and aimpoint) that only can be found in FFUR2007
- Kegetys' HiSky
None of them will work from the get-go, you will have to put some time and work to make all of them work together, but just read their readmes - it is much easier than you think but still time consuming.
You can find all of them (apart from what I've mentioned) on OFPR.info I think and even more - there are many better unit/vehicles models at that site (Search by ORCS, BAS, RHS, INQ and SEP - they've made many great models).
As for FPS - well considering 2km viewdistance on a not very good optimized OFP engine it is playable on a system with 3+ years old parts and can be playable on a system with 5+ years old parts if you will make grass density lower.
Incredibly atmospheric Autumn Nogova island + the above
SJB Weapons Pack texture detail overkill
Also Nogova replacement for OFP: Resistance, comes with modded Res campaign, so you can complete it with the new island. The upper screen shows NIM Dynamic Weather.
