I played Far Cry one and two and never had any problem. By your question, does that mean you are not having any lag issues ?
No lag for me here in Canada, maybe lag hates snow too???
Anyways EU gave me lag back in 2014 but I kept using those settings on new PC since 2015...
Client loader settings:
- disabled streaming audio
- set my connection speed lower then my max (test w/ speednet) ie. if 8Mbps then choose 4Mbps or lower.
- oddly found Download thread count of 10 performed better then 12 for me back in 2014
- Tab - Planet Data I've uncheck the planets/areas I won't visit any time soon.
I also turned off QoS in my router back then which seemed to help EU limp along faster. Normally I would've made QoS exception rule but was doing a lot of testing back then and QoS didn't make much difference for other applications for me so I've left it off ever since.
Yes I should probably retest it all, but I found it to be such a hassle with EU back then. And nothing else gives me lag even unoptimized sd/alpha/beta games, nor old or new games.
I recall my tracert/traceroute back in 2014 showed only a slight bottleneck from a backbone (tier 1 isp) somewhere between Sweden and I. But not enough to unsafely use a vpn tunnel to proxy the data packets around it.
If after all that your still having same amount of lag then maybe look into your ISP for doing throttling/rate limiting or other "QoS measures"??
