We need to find solution to remove OnGameFrame for that simple task.

For this simple matter of code, there's no harm in it running OnGameFrame. The only other solution that comes to mind is a timer that fires before a grenade explodes and calls itself every 0.1 seconds until the grenade actually explodes.

While I cannot for the life of me find the post to link you to it, it roughly describes everything that's occurring during an OnGameFrame call. If memory serves me correctly however, it loops through all clients in-game at least twice, all of the entities, and a few other things. That being said, the server can handle a few additional calls to OnGameFrame, especially something as light as this. It's when you get several plugins calling it, or plugins doing a lot more than they should, that you'll run into lag issues.

I think it should be another way.
Where is engine get default values for nade radius and demage from? Maybe there is special entity, or maybe we should set some property of hegrenade too, not only on hegrenade_projectile etc.

OnEntityCreated fires before the entity spawns, you need a spawn hook, it doesn't seem to work on all entities so you may need to change the values on the next gameframe or at latest 0.1 seconds with a timer. also you only need to change the radius and damage once as they don't get reset (well the last time i checked).

You can use my StickyNades Lite plugin to modify your grenade damage and radius. It uses a SpawnHook instead of using OnGameFrame.
