About the Topspin. Yes, with too high Topspin setting, it seems unrealistic. BUT, it is mainly for only the topspin strike. Other shots are ok. Basically, if I set either me or CPU Topspin setting over 40%, the topspin strike becomes too loopy. All the other shots are ok; it is just the topspin strike. Which makes it even more difficult to put a player as Defender, because Defender even gets an added bonus to the already loopy topspin strike. I wish there would be a separate setting for the topspin-only strike, which could be modified. This would fix things greatly. Because sometimes I want to put the global Topspin setting at a higher percentage (I keep at around 30-35% for both me and CPU), but anything higher results in the topspin strike becoming unrealistically loopy. (In Devmode, "Spin" value anything over 65).
And for the speed, I use MTRUN when playing against the CPU (I raise acceleration, but I lower maxspeed down to 0.80), so I am able to set this value in the .ini, and then break it down more to get it just right by modifying the Speed setting in the Character Sheet. But I would also like to be able to modify the CPU's speed in the .ini. I play in incredible mode, and I have the CPU speed set to 0%, but he is still pretty fast. But I play on incredible because I like the CPU to hit really hard and be very consistent. It would be great if you could add a setting in the .ini to also be able to modify the CPU's speed (acceleration and maxspeed), in addition to the current Speed setting in the Character Sheet.
I'm telling you, with each update and each new setting that you allow to be modified, Manu, the game has become greatly realistic, comparing it to real-tennis and on TV. Sometimes its even hard to tell the difference when watching on TV (except for some graphics

). I really hope that you can consider these 2 things, because this would, in my view, put it on par to the real thing. Graphics, can wait till another day (tho hopefully not too many years

).
