This was great. Sync is not the best yet, compared with VCMP and SAMP counterparts, but a huge step ahead and finally enjoyable gunplay. Great to see that most issues plaguing T3 have been fixed. And car damage brings a lot of fun into the server!
I have played for 6 hours straight and
did not crash even once. My session continued flawlessly since I joined. Kudos to the development team.

Strangely, my FPS was playable in EFLC with better graphics, while I can only play with playable FPS in regular IVMP only if I set all settings to low.
I did have several problems launching the client, however, that I managed to fix and get into the game after a lot of tinkering.
First things first - if you have the Steam version, verify the game cache to make sure that you don't have invalid/corrupted files. Steam will detect if anything's wrong and will install the missing/corrupted files. Once that's done, you'll have the most up to date version, so you need to download the 1.1.2.0 patch and downgrade the game. Simple - just open the updater and let it install.
Upon these steps I was able to launch the IVMP, but upon logging in my map wouldn't load. I fixed this by using a certain commandline. Use these parameters:
-availablevidmem 4.0
-framelimit 0
-norestrictions
-novblank
-ReservedApp 0
-memrestrict 943718400
-refreshrate 60
These are the steps that let me finally play without problems.
