You can use Alt+F5.can we have more fps like in AoeHD? there with command in chat line you can set up max and min FPS, and also when press F11 you can see in how much FPS game is running, with this option slower PC can set up low FPS to no affect them,
If you ever get lag in multiplayer on v1.5, please ask the host to press Alt+F5 only once to display rate stats next to the game clock. It takes a moment to appear, so please don't press it more than once or it will toggle off again. The mt stat is cpu lag and the mp stat is network lag. Players other than the host will not see the mt or mp stats. The second number of each pair is the player slot number that is currently causing the worst performance for the stat. For mt (cpu lag), the first number should usually be below 10 when the game starts and increase slowly toward maybe 15-20 later on. For mp (net lag), the first number is just their ping. If mt is 20+ at the start of the game, something is almost certainly wrong with that player's system or game options (using 32-bit color or not using it depending on GPU driver support, excessive screen resolution for their system, running animated water on a slower system, etc.).
Note that the player slot number isn't the player color, so please see the order of names on the diplomacy window to find out which player it is, where 1 is the first slot, etc. Lag like that is usually cpu related, so it may be caused by someone having excessive cpu load in the background, etc. Will look into the rec, thank you!
